Gravity pulls objects toward the center of the Earth.

Front

What is the term for the change in motion of an object due to a force?

Back

Acceleration is the change in motion of an object due to a force.

Front

What is the relationship between mass and gravitational force?

Back

The greater the mass of an object, the stronger the gravitational force acting on it.
