Distinguish between the concepts of velocity and acceleration, using a bowling ball's behavior as an example for each.
 
  What will be an ideal response?

Question 2

Galileo said that if you rolled a ball along a level surface it would
 
  A) slow down due to its natural tendency to come to rest.
  B) keep rolling without slowing down if no friction acted upon it.
  C) roll as long as its inertia nudged it along.
  D) eventually roll in the opposite direction.

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.
