2. / The net work done by a conservative force on a particle moving around any closed path is _____.
4. / a place where KE=0 and the particle changes direction.
6. / A transfer of energy from the system.
8. / The primary test for determining whether a force is conservative or non conservative is ________.
9. / The energy associated with the state of separation between two objects that attract each other by gravitational force
16. / The sum on the system's mechanical energy, thermal energy, and any type of internal energy in addition to thermal energy.
18. / when the particle is at a reference point

1. / the gravitational potential energy is dependent on it
3. / The point at where a particle is moved slightly left or right and a restoring forces appears, that moves it back to its original position.
5. / The change in energy over the change in time.
7. / The sum of a system's potential energy U and the kinetic energy K of the objects within the system.

14. / The energy that is associated with the state of compression or extension of an elastic object.
15. / A force that is not conservative is called ________ _______.
17. / What is the energy transferred to or from the system?
