Same as 9 What would the displacement vs time graph look like? Sketch a rough copy of it. Same as 9. What is the difference between instantaneous velocity and average velocity? Instantaneous is the exact velocity right now while average is the velocity over time.. What speed does the speedometer of a car read, instantaneous or average? Instantaneous. Distinguish between speed and velocity. Speed is the magnitude of the distance over the time. Velocity is the magnitude and direction of the change in displacement over time.. Why does the unit of time enter twice in the unit of acceleration? It is the rate of change of velocity.. Define displacement. Give an example. The change in position of an object from its initial position to its final position. Page 8 of 9
Chapter : One Dimensional Motion. Distinguish velocity and acceleration. Velocity is how fast you are going while acceleration is how fast you are getting faster. 7. Is a fine for speeding based on one s average speed or instantaneous speed? Instantaneous speed. Page 9 of 9
