Why don't we get pulled towards the Sun when we jump?

• Because the Sun is too small.

• Because the Sun is too far away.

• Because the Earth is closer.

• Because the Sun has no gravity.

What keeps the Earth in orbit around the Sun?

• The Earth's rotation.

• The gravitational pull from the Sun.

• The Earth's atmosphere.

• The light from the Sun.

How do we show the force of gravity acting on an object in a diagram?

• By drawing a line under the object.

• By drawing a circle around the object.

• By drawing an arrow pointing away from the object.

• By drawing an arrow from the object's center towards the Earth.

What is the relationship between the size of force arrows and the force they represent?

• Arrow size does not matter.

• Arrows are always the same size.

• Larger arrows mean larger forces.

• Larger arrows mean smaller forces.
