Across
- 4. the force of attraction between all masses in the universe
- 7. equal forces acting on an object that combine and form a net force of zero
- 8. A measure of the amount of matter in an object
- 11. occurs when two solid surfaces slide over each other
- 13. The tendency of an object to resist a change in motion
- 14. For every action force there is an equal and opposite reaction force
- 15. friction that occurs when an object rolls over a surface
- 16. Friction that acts on objects that are not moving
- 17. Change in velocity divided by the time it takes for the change to occur
- 18. the force or speed with which something moves (mass x velocity)
- 19. a force that acts on a body moving in a circular path and is directed toward the center around which the body is moving.
Down
- 1. the scientific law that states that an object at rest will stay at rest and an object in motion will stay in motion with a constant speed and direction unless acted on by a force
- 2. Fluid friction acting on an object moving through the air
- 3. Force equals mass times acceleration
- 5. The greatest velocity a falling object can achieve
- 6. friction that occurs as an object moves through a fluid
- 9. Forces that produce a nonzero net force, which changes an object's motion
- 10. A push or pull exerted on an object
- 12. The sum of all forces acting on an object
