- 2. the product of the force and the time over which the force act on an object
- 6. The curved path that an object follows when thrown,launched,or other wise projected near the surface of earth
- 7. an action exerted on an object which may change the objects state of rest or motion
- 11. the acceleration directed towrd the center of acircular path
- 14. a single force whos external effects on a rigid body are the same as the effets or sever alactual forces acting on the body
- 16. the energy available for use when a deformed elastic object returns to is original configuration
- 17. the energy associated with an object because of the position,shape,or condition of the object
