Force and Motion

3. A machine made up of more that one simple machine.
6. A push or pull exerted on an object in order to change the motion of the object.
7. A force attraction between objects that is due to their masses.
10. A measure of the gravitational force exerted on an object.
12. The transfer of energy to an object by using the force that causes the object to move in the direction of the force.
15. Distance traveled per unit time.
16. For every action force, there is an equal and opposite reaction force.
17. The unit used to express energy.
18. The force action in an object equals the object's mass times its acceleration.
19. A number that tells how many times a machine multiples force.

1. The work done on a machine; The product of output force and distance force is exerted.
2. A measure of the amount of matter in an object.
4. If an object is at rest its stays at rest and and object in motion stays in motion unless an unbalanced force acts upon it.
5. The rate at which work is done or energy is transformed.
8. Make work easier for us by allowing us to push or pull over increased distances.
9. A quantity, usually expressed as a percentage that measures that ratio of work output to work input.
10. The work done on a machine; The product of the input force and distance force exerted.
11. A force that opposes motion between two objects that are touching.
13. A device that helps do work by either overcoming a force or changing the direction of the applied force.
14. The speed of an object, in a specific direction.
