Forces and Motion

2. A push or pull that acts on an object
4. using force to move an object
6. the force one object applies to a second as in Newton's third law of motion
7. consists of a rigid bar that rests on a pivot point
8. arm the part of the lever you apply an input effort force
9. an inclined plane that is used as a tool for cutting or separating things
10. forces forces that do not cancel each other out when acting together on a single object
13. arm produces an output force to lift the load
15. The speed and direction of a moving object
16. a wheel with a groove in the rim
18. plane a flat, slanted surface that makes it easier to move heavy objects to higher levels

1. How fast an object's position is changing with time at any moment
2. Opposes the motion of one object moving past another
3. The tendency of an object to resist a change in its state of motion
4. and axle a large-diameter wheel rotates in a circle around a small-diameter axle
5. an inclined plane wrapped in a spiral around a cylinder or cone
11. forces forces that cancel each other out when acting together on a single object
12. A change in velocity
13. the force with which an object responds to an action as in Newton's third law of motion
14. machines devices with few moving parts that make work easier to do
17. where the lever rests
