Work(Done):
Explain? Always start sentence with "work is done when" instead of "work done refers to"
Ans: Work is done when an object moves in the same direction as the force acting on it.

Work Done = Force x Distance
  
WD=FD
SI unit: Joule, J

KE (Kinetic Energy)
The ability to do work due to the object's speed.

KE= half x m x v*2

m--Mass
v--Speed

GPE (Gravitational Potential Energy)

The ability to do work due to the object's height.
*GPE can also be said as PE.

PE= m x g x h

m--Mass
g--acceleration due to gravity (may be provided by question)
h--height (distance)

CG (Centre of Gravity)
Refers to the Location/Point through which the weight of the object acts through.
-Point of CG = Point of Centre of Mass
-When a cutting through the CG Point, the 2 seperate pieces will have equal mass/weight.

Equilibrium

1) Stable Equilibrium

-An object will return to it's original position after being displaced(Hit/pushed)

2) Unstable Equilibrium

-Object will be unstable falls..

3) Neutral Equilibrium
The object will roll away after being displaced(Hit/pushed)



How to Increase Stability?
  1. Increase Base level.
  2. Decrease CG (Centre of Gravity)

ELECTRICITY AND MAGNETISM
 
Properties of Magnets:
  1. A freely-suspended magnet will always come to rest in a North-South direction.
  2. The North pole of the Magnet will always point at the north,South pole of magnet will point at the South.
  3. Magnetic attractions are strongest at the poles>>not exactly the ends of magnet. **Distance between poles in 5/6ths the length of the magnet.
  4. Iron,cobalt,nickel,steels are called magnetic materials because they can be attracted by magnets.
  5. Magnetic materials can be made into magnet but non-magnetic materials cannot.
  6. Like poles repel while unlike poles attract.
  7. To test whether a speciment(material/object) is a magnet or a magnetised magnetic material, use Repulsion method.
  8. Poles- Locations where there is strongest magnetic effects

How to Prove Magnets??

>>Only when same poles is able to repel.

Note that when drawing the lines/arrows, it must always be from the North to South direction!!

Magnetisation

Practical Electricity

A.C. :Alternative Current
D.C. :Direct Current

Neutral is alway 0V
Live is between 230V--240V
  • When there is current in Live wire, there will be current in Neutral wire
Fuses


Function of a fuse:
A fuse is used to cut off the current supply when excessive current flows through it.
  • To protect the equipment/appliance from damage.
  • To prevent wires from overheating;may led to electric fire.
***Available fuse Values(Need to remember the values)
1A, 2A, 5A, 10A, 13A, 15Azz

**A Fuse is always connected to the live wire!
Ans: When excessive current flows,the fuse blows and the appliance will be isolated from high voltage.

Electrostatics

(Static Electicity)

Static Charge and Electric Current

a)Current Electricity is the type of electricity where charges are flowing.

b)An electricity is actually an external flow of electrons(Negative) from the negative pole to the positive pole.

c)Direction of electron flow is opposite the direction of the conventional current.

2. Insulators-Materials that electricity cannot flow through.
    Conductors-Materials that allow electricity can flow through.

3) Current is measured as the amount of electricity Charge flowing in unit time.
Thus an electric current is the rate of flow of charges

4) Unit of Charge: Coulomb (C).

5) Formular of current,charge and time:
        Current=(Charge  Time)

-Express in Symbols, Q= IXS

6) Current of 1 ampere(A)= Charges flowing at the rate of 1C/S.

7) Instrument used to measure current is Ammeter,Connected in series.


2 Properties of Charges:

1) 2 types-Positive(+ve), Negative(-ve)

2) Like Charges repel while unlike charges attract.

**Only Negative Charges(-ve) moves.

Applications:

  -Lightning Rods

  -Electrostatic

  -Spray painting

Current Electricity

Current is the rate of flow of charge.

I = Q / t

I = Current

Q= Charge
t = Time


*Quest: Which of the following is a unit of current?

(a) J/S

(b) C/S

(c) S/C

(d) Volts

Ans: C/S


 Current direction

-->+ve to -ve (Positive-Negative)                        

*Note: Ammeter can be measured from any part of the circuit!

Ammeter;

-connection in series

-Ideal ammeter-zero resistance!


Questions:

1(a) Current electricity is the type of electricity where the charges are flowing/moving.

(b)An electric current is actually an external flow of electrons (Negative) from the negative pole of the
 battery to the positive pole of the battery

However, the direction of conventional current is taken to be the direction of flow of Positive charges.
(c) Thus, the direction of electron flow is opposite to the direction of conventional current.

              

2. Insulators are materials that do not allow electric current to flow through them while conductors allow electric current to flow through them.

3. Current is measured as the amount of electric charge flowing in unit time. Thus an electric current is the rate of flow of charges. 


*4.The unit of charge is the Coulomb(C).


5.The quantities current, charge and time a reconnected by the equation:

 Express in symbols, Q=           .
 

6. A current of one ampere (A) means charges are flowing at the rate of 1 C/s.


7. The instrument used to measure current is called the Ammeter and it is connected in series to a circuit.
-In a series circuit, there is only one single conducting path or loop.



Resistence,Voltage, Current.

SI UNIT:

Resistence-R
Current- I
Voltage- V=R

I


Resistence is measured in "Ohms".

1000Ohms=1Kilo-ohms OR 1K.


Current is measured in "Ampheres"(A)

1000miliAmpheres=1Amphere OR 1A.


Voltage is measure in Volts (V)


note:"/" = Over.
examp: 1/2 = half


Measuring resistence:

Types of Connection:

In series:
R1+R2+R3....=  
             .


In Parallel:
1/R1 + 1/R2 + 1/R3=      
           .

Example:
1/20 + 1/10 + 1/5    (change to same denorminators first)
=1/20 + 2/20 + 4/20
=7/20
resistence=20/7

***Important note!
When resistors connected in parallel, the total resistence of the resistors will always be smaller than the smallest value resistor!!!


Potential difference = Voltage.

Voltage- measure using Voltmeter  (connected in parallel)
Current-
measure using Ammeter  (connection in series) 


In a series circuit, the higher the resistence of the resistor, the higher the voltage flowing across it.

Unit 6.04
Melting,Boiling&Evaporating
      

3States Of Matter:
>Solid-has a definite shape and a definite volume,Shape is usually difficult to change.

>Liquid-Has a fixed volume.Flows easily;change its shape to fit the shape of its container.

>Gas-Has neither a fixed volume nor a fixed shape;changes its volume and shape to fix its container.Flows easily.
Note:Gases and liquids are called fluids.

Changes of state:

Change states:Needs heat energy

S-L=Melting
L-G=evaporating
G-L=Condensation
L-S=Freezing

*Melting
-Changes from solid to liquid
-For pure substance,melting occurs at a definite temperature.
-During melting process, Heat energy is needed to add into the substance.

*Freezing
-Changes from liquid to solid
-For pure substance,freezing occurs at a definite temperature.
-During melting process,Heat energy is taken away from the substance.

Effect of Impurities on the Melting Point of Water:
Any Impurities added to pure water lowers its melting(Freezing) point.
Example,100g of salt is added to 1000g of water,the melting point is lowered by about 4*C.

Effect of Pressure on the Melting Point of Water:
In general, the melting point of ice is lowered when it is subjected to pressure.

Because ice changes to water, its volume decreases.
If high pressure is applied to ice,it cause the volume to decrease and thus helps the ice to change to water.

*Boiling
-Boiling is the process in which a substance changes from liquid state to gaseous state.
-A pure substance boils at a definite temperature is known by its boiling point.
-Heat energy is needed to supply to the liquid.

*Condensation
-Changes from gas to liquid.
-A pure substance will condense at a definite temperature.

Effect of Impurities on the Boiling Point of Water:
Impurities added to pure water raise its boiling Point.
Example,100g of salt is added to 1000g of water, the boiling point of water is raise by 1*C.

Effect of Pressure on the Boiling Point of Water:
Usually,higher pressure applied to water will oppose expansion and therefore oppose boiling.
Hence,the boiling point of water increases the external pressure increases.

Changing Boiling Point:
If the air pressure is greater than 1 atmosphere,water boils above 100*C. If the pressure is lower than 1 atmosphere,water boils below 100*C.

*Evaporation
-As a liquid warms up,the average speed of the molecule in it gets larger.
-However,not all molecules moving with same speed,some move faster & some move slower.
-Some molecules near the surface of the liquid have enough energy to escape.
-They evaporate from liquid to form a vapour,Process is called "Evaporation".
-Evaporation makes the liquid cooler because the faster(hotter) molecules escape,leaving behind the slower(colder) molecules.

Factors affecting the Rate of Evaporation:
1)Temperature:
Higher the temperature,faster the rate of evaporation.
2)Area of the exposed surface:
The larger the exposed area,the faster is the rate of evaporation
3)Humidity of surrounding air :
Higher the humidity,slower the rate of evaporation.
4)Pressure: The lower the external pressure,the faster the rate of evaporation.

Topic: Chemical Bonds
Updated on 14 Augest 2007


An atom have a nucleus which contains Protons and neutrons.
If An Atom:
  • gains electrons, it becomes positively charged Ions
  • Loses electrons, it become Negatively charged Ions
Isotopes- Atoms with same no. of Protons, Different no. of Neutrons.

Non-Metal + Non-Metal = Covalent Bond
Metal + Non-Metal = Ionic Bond

Ionic Bond
  1. High boiling and melting point
  2. Can conduct electricity in molten state
  3. Ionic compounds dissolve in water but not in Organic solvents
Convalent Compound
  1. Low melting and boiling point
  2. Cannot conduct electricity
  3. Can dissolve in water but not in organic solvents
  • Metals gives out electrons
  • Non-metals takes in electrons
Electronic shell must have a Electronic Configuration of 2.8.8...(In order to be stable)
2 = First Shell
8 = Second Shell
8 = Thrid Shell (If this is the outer shell then it must be 8 to be stable)

Unstable- 2.8.6
To make it stable, Just put in 2 more electron to make it 2.8.8 (Stable)
-The ion will be negatively charged after adding electrons.

Unstable- 2.8.2
To make it stable, simply take away 2 electrons from the 3rd shell to make it 2.8 (Stable because outer shell is 8)
-The ion will be positively charged after losing electrons.


Topic:Metals and Their Extraction 1


*Physical Properties Of Metals
  1. High boiling point.
  2. Conduct electricity
  3. Shiny,Can be polished
  4. Malleable,Can be bend without break.
  5. Ductile,Can be stretch
  6. High Density
*ALLOYS

An alloy is mixture of metals and other element.
Usually metallic element.
e.g: Brass,Bronze...

Properties of an Alloy
  • Alloys-much harder and stronger than pure metals.
  • Pure metals are too soft because the layers of atoms can easily slide over one another.
  • Alloys are harder and stronger because the atoms of two metals are of different sizes thus it is harder for them to slide over each other.

New Chapter(Title coming soon)

Multi-National Corporations (MNCs)/Trans-National Corporations

- They are large buisiness organisations that have offices and factories in many countries.
eg. Japan--Toshiba, Sony, Mitsubitshi
      USA--   Microsoft, Ford, Dell, Nike
      Britain-B.P,Shell

Reasons why the MNC shift out from their home countries..
  1. Labour costs in other countries are cheaper
  2. Developing countries are usually strike-free(Uninterupted Production)
  3. Availability of raw materials in developing countries.
  4. Economies of scale--> the company breaks up the production
eg. Ford: Engine-Mexico              
               Car Body- Cubn

Possible N-Levels Question:
Q: Why do developing countries want MNCs to locate in their countries?
  1.  MNCs provide employment for the local populations.
  2. These jobs helps to increase salary which increses standard of living.
  3. MNCs pay taxes to the government and used in developing the country.
  4. MNCs share technologies with the local companies.
  5. MNCs contribute to charities.
  6. MNCs work with local industries eg: Mitsubitshi Motors provide car engines for Proton cars in Malaysia.

**Possible problems caused by MNCs to developing countries:

  1. MNCs may shift out their operations to other countries offering cheaper production costs.  This results in lose of jobs.
  2. They may cause pollution to countries where the environment laws ae weak.
  3. May become too powerful and control the government! eg. Shell controls the oil industry in Nigeria,government is afriad of Shell.
  4. MNCs who are bigger will cause local industries to become bankrupt.

Space Shrinking Technologies
eg. e-mail,airplane

-Instant communication like e-mail & long distance phones have enabled businesses to
relay messeges instantly to other business far away in other countries.


Unit:Plantation


 
BENEFITS OF PLANTATIONS
  1. Create Jobs/employment to>100,000 malaysians.
  2. Help raise standards of living.
  3. Plantation provides raw materials for other industries eg.Cooking Oil.
Problems
  1. Shortage of labour
  2. Competitor from other substitutes such as soybean.
Solutions
  1. Hire foreign workers like Indonesians.
  2. Automate-Machines to replace workers.
  3. Research to improve palm.
  4. Advertise overseas.
2 of the few processes of Palm Processing
Palm tree:


  • Transport: Oil palm fruits have to be processed on the day of harvest to minimize the accumation of fatty acids which will make them spoil.
  • Sterilisation:  Harvested fruits are sent to be sterilized by steam at about 1400*C between 75--90minutes. It loosens the fruit and aids in extraction of the oil.

Unit:Changing Tourism
 
1.(a) (i)Define "tourism".
It refers to the movement of people to other places to engage in leisure activities.

(ii) Distinguish between "domestic" and "international" tourist.
Domestic tourists refers to visitors who visit tourist attractions within their own country wheras, international tourist refer to visitors who visit another countries to engage in tourist activities.

(b) 4 reasons people travel:
  1. To seek leisure/pleasure.
  2. Buisiness purposes
  3. Travel for pilgrimage-e.g haj
  4. Visit Friends,relatives.
1)With reference to examples which you have studied,describe the 4 "A"s that make up an attracting tourist destination.
Ans:
^Attraction refers to anything that attracts tourists.

In Singapore,there are 4 types of attractions, namely: Natural, Man-made, Cultural and Event Attractions.

For natural attractions people like to enjoy the warm sun in Singapore.Some enjoy hiking up Bukit Timah Hill. As for cultural,places like Little India and Chinatown have traditional arts and crafts to attract tourists.
Man-made attractions are artifically created with certain themes e.g. Zoo and latest would be two Intergrated Resorts(IR). Singapore also continue organising events throughout the year to draw tourist such as concerts,musicals and festivals like Chigay,as well as sports event.



Factors Of Tourism:

     
*Attraction:
>Natural
>Man-made
>Cultural
>event

*Accessibility-A ease by which a place can be reached.(S'pore)

  • Increasing world populaton.
  • Better Technology like bigger planes which provide cheaper airfares and more remote destinations can be easily reached.
  • More people travelling for business networking.
  • People becoming more educated so are more curious which increases desire to travel.
  • More people living in busy cities and want to get away from stressful lifestyle.
  • Internet connection allows travellers to plan & book their trips online(more convenience)
Q: Which country has the highest number of tourist to S'pore?
Ans: India

Q: What is the role of the STB? (S'pore Tourism Board)
Ans:
  • Campaigns to draw tourist here. e.g. "Uniquely Singapore"
  • Work with private sectors to organise events. e.g. "Great Singapore Sale", Light-up at Orchard Road.
  • Advertise overseas.



Environment Input of Tourism

Positive


1) Convert old buildings like thoses at Clarke Quay into tourist attractions> preserve the old buildings.
 -Alfresco Dining  (Outdoor)

2) Encourage the cleaning up of the environment.
eg. Singapore River clearing up since 1980 to a river that can be used for leisure activities.

3) Promote conservations of old buildings eg.Little India,Geylang serai.


Negative

1) Mass tourism lead to pollution in the environment.
2) The taking of seashells,corals can destroy the natural environment.
3) Forest are cleared when hotels are build,this causes plants to be destroyed and animals to become extinct.




Social-Cultural Impact:

Positive
1) There will be a mixing of locals and tourists. They will learn to respect each other's culture.
   -important in a multi-racial society like S'pore.
2) Make tourist more proud of their culture when tourist admire their buildings.

Ecotourism


Important questions that is common in exams!

(a) Define term "ecotourism" (What is ecotourism)

Ans: Ecotourism is defined as responsible tourism to natural places without damaging the environment. Tourists travelling between the areas can use bicycle instead of private car.


(b)(i) How tourism can be responsible without damaging the environment.

Ans: When visiting the National Parks,use public transport or ride bicycle or take a boat
to reduce the pollution to environment.

   (ii) How tourism can also be seen as an educational experience.

Ans: Staying in farms is an educational experience as it allows tourists to experience & learn how farmers live and work.

   (iii) How tourism benefited the local people?

Ans:Tourists are encouraged to buy products that are locally made instead of these made from factories.This helps to stimulate the local environment.

Sustaining Singapore's Development In The 21st Century


External Factors that affect singapore:


  1. Economic Slowdown

    -Singapore is highly dependent on her trade with other countries so if there is a slowdown in other country, singapore will be affected.

    eg. When there is a currency crisis in Southeast Asia,

    S'pore was affected.

  2. Social-Political unrest in other countries

    -S'pore have to bear the blunt of war even if they were not started by Singapore.

  3. Environment Crisis.

    -Air and Water pollution that drift towards S'pore will affect the lives of people and operation of business.

    eg.Haze from the Indonesian forest fires cause the people living in Singapore to fall ill and also increased the prices of vegetables from Malaysia as their plantation agriculture products were affected.



Economic Strategies for Sustaining Development

>>Movement towards a Knowledge-Based Economy


  1. Improving Worker's Employability

    -Workers are encouraged to upgrade their skills to remain employable.

    -NTUC pays 80% of the training costs for retrenched Union workers.

    -Workers are encouraged to be well-equipped with Information Technology (IT)

  2. Importing of Foreign Technologies

    -Encouraging Multinational Cooperations to operate in S'pore as they can share technology with the local companies.

  3. Attracting Foreign Talents

    -Attracting foreign talents can help S'pore build up her network talent around the world

  4. Promoting R&D

    -Necessary because S'pore needs to develop her own tlent pools and create her own technologies.

  5.   Creation of IT Infrastructure

    An up-to-date IT Infrastructure will enhance the competiveness and efficiency of Singpore.



Environment Strategies

  1. Improving Infrastructure for waste deposal

    -There are six plants for treatment of human waste.

    -They are compact and covered structures build by the government and helps to save space and reduce foul smells.

  2. Using improved Technology and Processes

    -They provide a cleaner environment

    -eg. Nature gas with lesser pollutants are used in power stations.

  3. Preserving Nature Sites

    -5% of the land in S'pore are preserved as nature sites.

    -These sites house a wide range of natural habitat which can be used for recreation, eduacational and scientific research


Summarised Notes for Sri Lanka

Reasons for Sri Lankan Conflict:


  1. Citizenship Rights

    -After Sri Lanka gained independence, the Tamils lost citizenship and became stateless.

    -Granted Citizenship only to those born in Sri Lanka or grandfathers were born there.

    -Indian Tamils were denied basic rights such as voting and yet they continue to work and contribute for the Sri Lankan Economy.

  2. Jobs in the Government Service

    -English-educated Tamils could enter the government service and get promoted.

    -The Sinhalese who does not know english could not enter.

    -To improve position of the Sinhalese,the Sri Lankan Government made Sinhala the only language of administration.

    -The Tamils were given 3 years to learn Sinhala or be dismissed.

    -Tamil is then made the language of administration in the Northern & Eastern Provinces where there are more tamils.

  3. University Criteria

    -There was an equal number of Sinhalese and Tamils in the same courses, numbers are not proportionate to the population in the country.

    -Changes were made to the criteria to allow more Sinhalese students to enter these courses.

    -Tamils were unable to obtain necessary academic qualifications needed to secure jobs.


Consequences of Conflict:


  1. Armed Conflict

    -Tamils turned violent when their demands were still not met and still be treated as second-class citizens.

    -Tamil United Liberation Front was formed as demanded for separate state called “Tamil Eelam”.

    -Demands Rejected>> Tamil youths form “Tamil Tigers” and started attacking the Tamils who did not support them then the Sinhalese.

  2. Economic Problem

    -Bread winners in families are killed in riots.

    -Massive unemployment among the factory and plantation workers.

    -Fall in tourist arrival which led to unemployment

    -Loss of foreign investment; Investors not confident.
