Physics

2. is defined as the rate of change of velocity, or the change in velocity per unit time.
8. of an object is the the rate of change of its position with time or the magnitude of the change of its position per unit of time
9. describes objects moving in straight lines
10. is a scalar quantity that refers to "how much ground an object has covered" during its motion.
11. in physics is a quantity that has both magnitude and direction
12. is a vector whose length is the shortest distance from the initial to the final position of a point undergoing motion

1. consists of an abstract coordinate system whose origin, orientation, and scale are specified by a set of reference points
3. The quantity that tells us how fast an object is moving anywhere along its path
4. is defined as the change in position or displacement divided by the time intervals in which the displacement occurs.
5. are quantities that are described only by a magnitude
6. generally refers to the quantity or distance. In relation to the movement
7. is a continuous function of time and gives the acceleration at any specific time during the motion.
