To understand conservation of mechanical energy involving gravitational potentia

Question

To understand conservation of mechanical energy involving gravitational potential energy and kinetic energy. For this problem, use the PhET simulation Energy Skate Park: Basics. This simulation allows you to explore the motion and energetic of a skater riding along a track. Where on the track is the skater's kinetic energy the greatest? The skater's kinetic energy is at its maximum value at the locations where the skater turns and goes back in the opposite direction. the same everywhere. at its maximum value at the lowest point of the track.

Explanation / Answer

A)The skater's kinetic energy is maximum at the lowest point.

Since at the lowest point all the energy that the skater has is kinetic energy only, PE at the lowest point is zero since, h = 0. So the skater has maximum KE at the lowest point and maximum PE at the heighest point.
