Gravity in the solar system 1

Front

What happens to gravity as two objects move farther apart?

Back

The less gravity they will have.

Front

What two factors does gravity depend on?

Back

Mass and distance.

Front

What is mass?

Back

The amount of stuff (matter) an object has.

Front

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

Back

It would crash into the sun.

Front

What does a large mass indicate about an object's gravity?

Back

A lot of gravity.

Front

How does distance affect gravitational pull?

Back

The greater the distance, the weaker the gravitational pull.

Front

What is the relationship between mass and weight?

Back

Weight is the force of gravity on an object, which depends on its mass.

Front

What is inertia?

Back

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

Front

How does gravity keep planets in orbit?

Back

Gravity pulls planets toward the sun, while their inertia keeps them moving forward.

Front

What is the gravitational force between two objects?

Back

It is the force that attracts them toward each other, depending on their masses and distance.
