PHYSICS VOCAB

4. Two Substances are at the same temperature
6. the study of the relations between heat, work, temperature, and energy.
9. energy that comes from a source and travels through space at the speed of light
10. a type of wave that travels in the direction of the medium
12. the degree of disorder or uncertainty in a system
13. The process of transferring heat through air or lquid
14. in an isolated system the total momentum of two or more bodies acting upon each other remains constant unless an external force is applied

1. a collision in which there is no net loss in kinetic energy in the system as a result of the collision
2. Materials that do not allow electricity to pass through them
3. the change of momentum of an object when the object is acted upon by a force for an interval of time
4. motion in which all points on a wave oscillate along paths at right angles to the direction of the wave's advance
5. when heat moves from one object to another object through direct touch.
7. all the energy contained in an object, including both kinetic energy and potential energy
8. product of the mass of a particle and its velocity
11. A collision where kinetic energy is not conserved
