Across
- 3. formula f=ma
- 7. friction in which two surfaces aren't moving past each other
- 9. how far an object has traveled
- 11. friction where two surfaces slide past one another
- 14. friction like force that opposes motion of objects that move through air - depends on speed, size, and shape of object
- 16. includes speed of an object and direction
- 17. anything thrown or shot through air
- 18. any two masses that exert attractive forces on each other
- 19. speed that doesn't vary
Down
- 1. measured period of an action
- 2. friction between a rolling object and the surface it rolls on
- 4. formula m=f/a
- 5. gravitational force exerted on an object
- 6. speed at any given point in time
- 8. formula a=f/m
- 10. the force that opposes the sliding motion of two touching surfaces
- 12. tendency of an object to resist any change in its motion
- 13. total distance traveled/total time
- 15. friction when object moves through fluid, meaning either a liquid or gas
- 20. the distance and object travels per unit of time
