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

FORCE

PULL e.g.• pull a door• open the door• wear a sock

PUSH e.g.• close the door• push the trolly• switch off the light

CONCLUSIONA FORCE CANNOT BE SEEN

BUT ITS EFFECTS CAN BEOBSERVED

The Effects ofA Force

Change the shapeOf an object

Change the directionof an object

Change the motionOf an object

Stationary to MovingMoving to Stationary

SpeedFaster to SlowerSlower to Faster

A type of force

Ways to increase

Ways to reduce Effects•Applying oil, grease or wax

•Using rods, ball

bearings and wheels

•Using air cushion

•Smoothening the 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 from slipping

•Stop a moving vehicle

•Keeps the position of a stationary objects

•Slows down the movement of objects

•Damages objects

•Produces unnecessary heat

What is?

Definition: Type of force that opposesthe movement of an object

Effects:1.Produces heat2.Opposes motion3.Causes wear and tear

Ways to reduce1.Using roller,marbles2.Using talcum powder, oil,wax ,grease ,air cushion.3.Smoothening the surfacesin contact

Ways to increase1.Increase the roughness of surface2.Increase the weight of object3. Change the shape of object

Advantagese.g: prevents from slipping,stop a moving vehicles

Disadvantagese.g: slow down the movement, damaging objects.

FRICTION

Group 15

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

SPEED

SPEED=DISTANCE/TIME

Food preservation

1.1 Understanding food spoilage

1.3 Realising the importanceOf 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 smellUnpleasant taste – sour tasteChanged colour – becomes yelliwishChanged texture - become curdMouldy – have dark spots

•State that microorganismsCan spoil food.

Carry out experiment e.g leaving a slice of bread in a plastic 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
