Gravity

Front

What is gravity?

Back

Gravity is a force that attracts two bodies towards each other.

Front

What does gravity cause objects to do?

Back

Gravity causes objects to pull towards one another.

Front

When is the gravitational force between two objects greatest?

Back

The gravitational force is greatest when the masses of both objects are large and they are close together.

Front

What is the SI unit of force?

Back

The SI unit used to measure force is newtons.

Front

How does mass affect gravity?

Back

Less mass equals less gravity.

Front

What is an example of gravity in action?

Back

An example of gravity in action is an apple falling from a tree.

Front

What role does distance play in gravitational attraction?

Back

The greater the distance between two objects, the weaker the gravitational attraction.

Front

What is the relationship between mass and gravitational force?

Back

Gravitational force increases with the mass of the objects.

Front

Can gravity exist in space?

Back

Yes, gravity exists in space; it keeps planets in orbit around stars.

Front

What happens to gravity on the Moon compared to Earth?

Back

Gravity on the Moon is weaker than on Earth, which is why objects weigh less.
