Back

The path an object takes as it moves around another object, such as the Earth around the Sun.

Front

What is mass?

Back

The amount of stuff (matter) an object has.

Front

How does distance affect gravity?

Back

The farther apart two objects are, the less gravity they will have.

Front

What happens to gravity if an object has a lot of mass?

Back

An object that has a lot of mass will have a lot of gravity.

Front

What would happen if the Earth didn't have any inertia?

Back

If the Earth didn't have any inertia (or wasn't moving), it would crash into the sun.

Front

What is gravity?

Back

A force that attracts two bodies towards each other.

Front

How does gravity affect planets in the solar system?

Back

Gravity keeps planets in orbit around the Sun.

Front

What is the relationship between mass and weight?

Back

Weight is the force of gravity acting on an object's mass.

Front

What is inertia?

Back

The tendency of an object to resist changes in its state of motion.

Front

How does inertia relate to gravity?

Back

Inertia helps keep objects in motion, while gravity pulls them towards other masses.
