Across
- 2. The force that opposes motion between two surfaces that are touching
- 6. Mass in motion
- 9. Friction caused by the surface of a moving object and air particles
- 10. Describes how fast an object moves
- 11. Describes a change in velocity
- 13. Describes how far something traveled
- 19. A combined force that does not cause movement
- 20. An object’s tendency resist motion
- 21. 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. When the only force acting on an object is gravity
- 3. All forces acting on an object at a given time
- 4. Newton's Law of Motion that states the unbalanced force acting on an object equals the object’s mass times its acceleration.
- 5. A push or a pull
- 7. A combined force that causes movement
- 8. The amount of matter within an object
- 12. Newton's Law of Motion that states Every action has an opposite and equal reaction
- 14. Newton's Law of Motion that states an object at rest tends to stay at rest, and an object in motion stays in motion until acted upon by an unbalanced force
- 15. The force on an object due to gravity
- 16. the force that causes everything to fall down
- 17. Describes how fast an object moves and the direction it is going in
- 18. How far something is from its starting point
