Front

Free fall:

Back

The motion of a falling object under gravity only.

Front

Gravity: A force of attraction between objects due to their masses.

Back

Front

Centripetal Force:

Back

A force that causes an object to move in a circle.

Front

Newton's First Law: An object at rest stays at rest, and an object in motion stays in motion at the same speed and direction unless acted upon by an unbalanced force.

Back

This law describes the behavior of objects in motion and at rest.

Front

Newton's Second Law:

Back

Force = mass × acceleration

Front

Newton's Third Law:

Back

For every action, there is an equal and opposite reaction.

Back

Correct Answer: Resistance between surfaces.
