1

Newton's second law of motion

Describes the acceleration of an object in the direction of the net force applied to it

2

friction

The force that opposes motion between two surfaces that are touching each other.

3

Gravity

Force exerted by every object in the universe on every other object. The amount of force depends on the masses of the objects and the distance between them.

4

centripetal acceleration

Acceleration toward the center of a circle by an object moving along a circular path

5

centripetal force

The force that causes an object moving along a circular path to move toward the center of the path.

6

weight

The measure of the force of gravity of an object.

7

Newton's third law of motion

Describes action-reaction pairs; for every action force, there is an equal and opposite reaction force.

8

momentum

A property of any moving object; the product of an object's mass and velocity.
