Force and Motion

4. space between two things
5. push or a pull. Force is what causes motion.
7. from one position to another
11. First Law-An object at rest tends to stay at rest, and an object in motion tends to stay in motion, unless acted on by an opposing force.
13. Third Law-Every action has an equal and opposite reaction
14. act of something moving, a change in position.

1. measure of an amount of atoms (matter) in something
2. force that acts in an opposite direction to movement. The more friction something has, the harder it is to move.
3. A change in velocity
6. Second Law-The greater the amount of mass an object has, the more force is needed to move it
8. imaginary line around which an object rotates.
9. force that attracts objects towards another object. On earth, gravity pulls us towards the center of the earth.
10. tendency of things to keep traveling in the same direction at the same speed, unless something stops them
12. The measure of the speed and the direction of a specific object
14. that has mass and takes up space.
