Answer to Question 1

Answer: Velocity is a measure of how fast something moves, while acceleration is a measure of how fast how-fast changes. A bowling ball rolling along a horizontal surface is an example of an object with constant velocity. It rolls without change. But if it rolls off the end of the supporting surface and falls, both its speed and direction change. It is then in a state of acceleration. Whenever an object changes its state of motion we say it accelerates.

Answer to Question 2

Answer: B
