Physics
Across
- 2. the speed of something in a given direction
- 6. any event in which two or more bodies exert forces on each other in a relatively short time
- 10. the total momentum of the two objects before the collision is equal to the total momentum of the two objects after the collision
- 12. a force that starts a body into motion
Down
- 1. part of the kinetic energy is changed to some other form of energy in the collision
- 3. there is no loss of kinetic energy in the collision
- 4. the impulse an object experiences during a collision is equal to its change in momentum
- 5. The property of any rotating object given by moment of inertia times angular velocity
- 7. ability of a deformed material body to return to its original shape and size when the forces causing the deformation are removed
- 8. the quantity of motion of a moving body
- 9. a quantity that has both magnitude and direction
- 11. the amount of matter or substance that makes up an object
