INVESTIGATING FORCE AND ENERGY

Theme : Force

Move a stationary object.

Pull

Friction

Push

Change the motion of object.

Change the shape of an object.

Types

Effects


11/25

FORCE

PULL

e.g.

pull a door

open the doorwear a sock

PUSH

e.g.

close the door

push the trollyswitch off the light

CONCLUSIONA FORCE CANNOT BE SEEN

BUT ITS EFFECTS CAN BE

OBSERVED

A type of force

Ways to

increase

Ways to reduceEffects

Applying oil, grease or wax

Using rods, ball

bearings and wheels

Using air cushion

Smootheningthe surface in

contact

FRICTION

Advantages Disadvantages

Roughen the

surface in contact

Heavier object

Shape of object

Produce heat

Opposes motion

Causes wear and

tear

Prevent fromslipping

Stop a moving

vehicle

Keeps the position

of a stationary

Slows down themovement of objects

Damages objects

Produces unnecessary

heat

What is?


14/25

Definition:

Type of force that opposes

the movement of an object

Effects:

1.Produces heat

2.Opposes motion

3.Causes wear and tear

Ways to reduce

1.Using roller,marbles

2.Using talcum powder, oil,

wax ,grease ,air cushion.

3.Smoothening the surfaces

in contact

Ways to increase

1.Increase the roughness

of surface

2.Increase the weight of object

3. Change the shape of object

Advantages

e.g: prevents from slipping,

stop a moving vehicles

Disadvantagese.g: slow down the

movement, damaging

objects.

FRICTION

Group 15


15/25

Movement

SPEED

Formula:

Speed = distance / time

Moves faster, shorter time

Moves faster, longer distance

Speed is a measurement of how fast an object moves

Solve problems using example

Food preservation

1.1 Understanding

food spoilage

1.3 Realising the importance

Of preserving food

Describe what spoilt food is* changes in appearance

* foods turn bad

* foods cannot last long

Unsafe to eat because

* expired date

* due to the action of bacteria

and fungi

Identify characteristics

of spoilt food.

Unpleasant smell bad smell

Unpleasant taste sour taste

Changed colour becomes yelliwish

Changed texture - become curd

Mouldy have dark spots

State that microorganisms

Can spoil food.

Carry out experiment

e.g leaving a slice of bread in aplastic bag

State the conditions for

microorganisms

to grow.

* air

* water

* nutrient

* suitable temperature- strong high kill bacteria and fungi

* suitable acidity

- cannot grow in a very acidic or

very alkaline

Give reasons why we need

to preserve food

* the food will last longer

* the food easy to store

* to reduce wastage of food
