2. the cause of acceleration or change in an objects velocity.
3. the greatest distance that particles in a medium move from their normal position when a wave passes.
4. any sound consisting of waves with frequencies higher than 20 Hz.
6. energy that is being stored.
7. the temperature at which an object's energy is at a minimal.
8. the bouncing back of a wave as it meets a surface or boundary.
9. the transfer of energy as heat between particles as they collide with a substance.
12. the distance traveled divided by the time interval during which the motion occurred.
13. the tendency of an object to remain at rest unless acting upon by an outside force.
14. a material through which energy can be easily transferred as heat.

1. the bending of a wave as it passes an edge or an opening.
5. energy that needs movement.
9. the transfer of energy by the movement of fluids with different temperatures.
10. a material that is a poor energy conductor.
11. the force between 2 objects in contact that opposes the motion of either object.
