Force and Motion

3. the force one object applies to a second as in Newton's third law of motion
6. A push or pull that acts on an object
7. Opposes the motion of one object moving past another
8. an inclined plane that is used as a tool for cutting or separating things
10. plane a flat, slanted surface that makes it easier to move heavy objects to higher levels
11. Often called the father of modern day physics.
12. a wheel with a groove in the rim
14. using force to move an object
15. forces forces that do not cancel each other out when acting together on a single object
18. the force with which an object responds to an action as in Newton's third law of motion
19. How fast an object's position is changing with time at any moment

1. The tendency of an object to resist a change in its state of motion
2. forces forces that cancel each other out when acting together on a single object
4. an inclined plane wrapped in a spiral around a cylinder or cone
5. A change in velocity
9. machines devices with few moving parts that make work easier to do
13. The speed and direction of a moving object
14. and axle a large-diameter wheel rotates in a circle around a small-diameter axle
16. consists of a rigid bar that rests on a pivot point
17. A force that pulls objects towards earth's center.
