Consider the track below and what you learned completing the Energy Skate Park Virtual Lab. Based on this information, select at which points the statements about the potential and kinetic energies of the skater are true.

A B C D E
Most kinetic energy

Most potential energy

Kinetic and potential energies are about equal (select 2 points)

In a track like the one described in the Energy Skate Park Virtual Lab, the distribution of potential and kinetic energy varies based on the skater's position. Here's a general breakdown of the points you might consider:

  • Most kinetic energy: This will typically occur at the lowest point of the track (often point D if the points form a hill-like structure).

  • Most potential energy: This occurs at the highest point on the track (which might be point B if the hill rises before descending).

  • Kinetic and potential energies are about equal: This usually happens at points where the skater is at a moderate height above the lowest point but not at the peak. In a typical track, this could be points A and C, assuming those points are midway up the track.

So, a likely selection would be:

  • Most kinetic energy: D
  • Most potential energy: B
  • Kinetic and potential energies are about equal: A and C

Please adjust the point letters according to the actual track layout if they differ from this description.
