Physics Unit 2 Vocab

2. Motion in which all points of a moving body move uniformly in the same direction
3. A hypothetical object having mass but no physical size.
4. In specifying motion, you must specify direction; drawn to serve as frame of reference
8. change in velocity divided by time taken to make the change.
10. A longer length of time can be divided into a number of shorter periods of time, all of the same length
14. Study of motion of objects and related concepts of force and energy
15. A physical quantity that has both a magnitude and a direction
18. total displacement divided by the time interval during which the displacement occurred
19. The change in position of an object; where you are versus where you started
20. the velocity of an object at some instant or specific point in its path
21. when the magnitude of the velocity is decreasing, and velocity and acceleration point in different directions.

1. the acceleration at any specific time during the motion
5. Something having position but not spatial extent, magnitude, dimension, or direction
6. Description of how objects move
7. the point or place where something begins, arises, or is derived
9. the actual time taken
11. Magnitude (numerical value) of how fast something is moving and direction in which its moving
12. Total distance traveled along its path divided by time taken to travel that distance
13. Force and why objects move
16. Measurements of position, distance or speed must have this
17. a physical quantity that has a magnitude but no direction
