1/17

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

2/17

Frictional force air exerts on a moving object

3/17

Ay object shot or thrown through the air

4/17

Acceleration toward the center of a circle

5/17

a property of any moving object

6/17

A net force acting on an object causes the object to accelerate in the direction
depends on: 1, size of force- more force = more A
2.mass of the object- more mass = less A

7/17

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

8/17

The greatest velocity reached by a faliing object

9/17

A law stating that the total momentum of a group of objects is conserved unless a net force acts on the object
