Physical Science
Across
- 2. the force that opposes motion for two touching surfaces
- 3. a push or pull applied to an object
- 4. speed in a given direction (vector)
- 6. how hot or cold an object is
- 8. acceleration with only the force of gravity acting on an object
- 11. between +,- charges
- 14. something that binds, fastens, confines, or holds together something
- 17. gives direction + amount
- 19. the speed of a reaction
- 23. to render more reactive
- 24. uses units of length to describe location of an object
- 25. the rate at which velocity changes
Down
- 1. an object used to measure motion
- 5. causes some radioactivity
- 7. the distance an object travels per unit of time note of changed position(scalar)
- 9. physical contact force
- 10. holds the nucleus together
- 12. occurs when an object changes position relative to reference point
- 13. how fast an object travels in a wave
- 15. how far an object has traveled
- 16. the capacity of vigorous activity
- 18. distance + direction of an objects change in position from a starting point
- 20. friction like force, oppose motion through the air
- 21. when two objects forcefully impact each other
- 22. non-contact, does not touch us
