Friction only occurs between solid objects.

Barriers stop things from keep falling.

Gravity stops acting when the object hits the ground.

Power, work, energy and force have different definition.

There is ‘more gravity the higher up you go’ because things dropped from a higher-level experience greater damage when they hit the floor.

An object floats because it has air.

When dropped in a vacuum, all objects will reach the ground at the same time.

Falling objects fall at constant speed.

Round things just move by themselves.

Not all metals are magnetic.

Magnetic forces can work in liquids.

Greater speeds increase air resistance.

Deeper water means better floating because there is ‘more water pushing on it’

All inflated balloons will float upwards.

Shadows have faces (we need to draw faces on shadows).

Copper coins are magnetic

The Earth lies at the centre of the solar system, with the sun and the planets orbiting around it.

Shadow is connected to us.

Things that have colour can’t be transparent.

Light comes out of the eye when we see.

Shadow is formed by reflection of light.

Gases don’t weigh anything.

Forces always act in pairs that are equal and opposite.

The moon is a source of light.

We have longer days in summer because the sun moves more slowly across the sky.

The moon’s diameter is just over a quarter of that of the Earth’s;

the sun’s diameter is about 109 times that of the Earth’s.

The sun moves around the Earth; this is why day and night occur.

A sound wave can never pass through a vacuum

Energy is a fuel.
