Forces and Motion

2. the force one object applies to a second as in Newton's third law of motion
6. forces forces that cancel each other out when acting together on a single object
7. and axle a large-diameter wheel rotates in a circle around a small-diameter axle
9. How fast an object's position is changing with time at any moment
11. A change in velocity
14. a wheel with a groove in the rim
16. plane a flat, slanted surface that makes it easier to move heavy objects to higher levels
17. arm the part of the lever you apply an input effort force
18. where the lever rests
19. using force to move an object

1. The tendency of an object to resist a change in its state of motion
3. an inclined plane wrapped in a spiral around a cylinder or cone
4. forces forces that do not cancel each other out when acting together on a single object
5. the force with which an object responds to an action as in Newton's third law of motion
8. Opposes the motion of one object moving past another
9. machines devices with few moving parts that make work easier to do
10. The speed and direction of a moving object
12. arm produces an output force to lift the load
13. an inclined plane that is used as a tool for cutting or separating things
15. consists of a rigid bar that rests on a pivot point
18. A push or pull that acts on an object
