Physics

4. When something moves.
5. Movements when an object's direction is changing. These would involve curved movements such as circular motion, or the motion of a ball being thrown through the air.
7. A force that holds back the movement of a sliding object.
9. If an object is moving, it is said to have what kind of energy?
10. F=MA
11. Scientists measure forces in units called what?
15. The universal force of attraction acting between all matter; gravitaion
16. Energy that is "stored" because of the position and/or arrangement of the object.
17. A push or pull.
18. For every action there is an equal & opposite reaction.

1. Numerical value in a specific direction
2. velocity at a split second in time.
3. How fast an object moves.
6. Product of the mass of a particle and its velocity.
8. A measure of how much the velocity of an object changes in a certain time.
12. Movements if you're moving in a straight line
13. the amount of something there is, and is measured in grams (or kilograms).
14. An object in motion tends to stay in motion; an object at rest tends to stay at rest.
