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