Mystery Science-Spaceship Earth #7-Gravity

Front

What is gravity?

Back

Gravity is a force that pulls objects toward each other. It is what keeps us on the ground and makes things fall.

Front

Why can you jump higher on the Moon than on Earth?

Back

You can jump higher on the Moon because it has less gravity than Earth, which means it pulls you down with less force.

Front

What happens when you jump on Earth?

Back

When you jump on Earth, gravity pulls you back down to the ground.

Front

Does gravity pull you into space if you jump?

Back

No, gravity always pulls 'down' towards the Earth, so you will come back down.

Front

What is the difference between gravity and magnetism?

Back

Gravity pulls on all objects with mass, while magnetism only pulls on magnetic objects.

Front

What happens to an apple when it falls to the ground?

Back

Gravity pulls the apple down towards the Earth.

Front

Is gravity an invisible force?

Back

Yes, gravity is an invisible force that we cannot see, but we can observe its effects.

Front

Can gravity act at a distance?

Back

Yes, gravity can act at a distance, meaning it can pull objects towards each other even if they are not touching.

Front

What would happen if there was no gravity on Earth?

Back

If there was no gravity, everything would float away into space, and we would not be able to stay on the ground.

Front

How does gravity affect the Moon's orbit around Earth?

Back

Gravity keeps the Moon in orbit around the Earth by pulling it towards the Earth while the Moon moves forward.
