Forces and Newton's Laws Review
Across
- 3. the point in an object that moves as if all of the object’s mass was concentrated at that point
- 10. states that forces always act in equal but opposite pairs: Newton's ________
- 12. the force resisting the motion when a body (such as a ball, tire, or whee) rolls on a surface
- 13. the combination of all forces acting on an object
- 14. two or more forces acting on an object that do not cancel and cause the object to accelerate
- 15. the resistance created by two objects sliding against each other
- 16. the amount of matter in an object
Down
- 1. states that if the net force acting on an object is zero, the object will remain: Newton's _________
- 2. the friction that exists between a non-moving object and the surface that it is resting upon
- 4. A push or pull upon an object resulting from the object's interaction with another object
- 5. states that an object acted upon by a net force will accelerate in the direction of the force, and that the acceleration equals the net force divided by the object’s mass: Newton's __________
- 6. the point at which the velocity of an object (the speed of change of the falling object) is no longer getting faster
- 7. force that acts to oppose sliding between two surfaces that are touching
- 8. two or more forces whose effects cancel each other out and do not change the motion of an object
- 9. rest or will move in a straight line with constant speed
- 11. the gravitational force between an object and Earth
