Across
- 1. resistive force that opposes the motion or past another object with contact
- 4. rate at which velocity changes with time
- 6. the speed at any instant of time
- 8. distance traveled divided by the time interval during the motion occurred
- 9. the product of the force exerted on an object
- 10. quantity describing both speed and direction
- 11. push or pull
- 14. the product of mass and velocity
- 15. a measure of how quickly work is done
Down
- 2. when objects collide in the absence of external forces
- 3. the absence of an external force, the momentum remains unchanged
- 5. stored energy due to position, shape or state
- 7. produces change of matter
- 12. combination of all the forces that act on an object
- 13. the product of force and contact time
