Look at the diagram of the roller coaster. Evaluate the relative potential energy at points 1-4. The height is in meters (m), Which two statements correctly describe the relative potential energy at various points on the track?

• At (1) the potential energy is greater than the potential energy at (3)

• At (2) the potential energy is greater than the potential energy at (3)

• At (3) the potential energy is greater than the potential energy at (4)

• At (4) the potential energy is greater than the potential energy at (2)

Answer explanation

At (1) and (2), the potential energy is higher than at (3) and (4), making the statements 'At (1) the potential energy is greater than the potential energy at (3)' and 'At (2) the potential energy is greater than the potential energy at (3)' correct.

Motion sensors on the ramp collect data on speed and kinetic energy.  The data is graphed above. 
What happens when the student moves from position A to B?

• speed approximately doubles

• kinetic energy approximately quadruples

• speed is reduced

• kinetic energy doubles

Answer explanation

When the student moves from position A to B, the speed approximately doubles and the kinetic energy approximately quadruples, while the speed is reduced.
