• How many different kinds of motions are there and
  what distinguishes them from one another?

Questions to ponder

• If we roll a car down a hill, will it move at
  constant velocity or will it accelerate? Why do
  you think so?
• Does the steepness of the hill make a difference
  in how the car will move? Why do you think so?
• How could we find out if your ideas are correct?

Follow-up Questions

• Is the velocity of the rolling car constant or
  does it change?
• How do you know?
• Is the velocity faster or slower at the start of
  the run?
• How do you know?
• Where is the velocity the greatest?
• Where is the fastest point in the cars travel
  down the ramp and across the floor?
