Across
- 5. A noncontact force that pulls objects toward Earth
- 8. Stored energy due to position
- 10. A type of speed that doesn’t change
- 11. A change in speed or direction
- 12. A push or pull on an object
- 16. A force caused by compressing or stretching an object
- 17. Forces that cancel each other out; no motion change
- 18. How fast something is moving

Down
- 1. Affects the amount of gravitational potential energy
