Question

HELP!!!!!!!!

Define mechanical energy. Using the example of the skateboarder on the half-pipe, explain how kinetic and potential energy relate to the mechanical energy at different positions.

Answer 1

When the skateboarder is at the top of the half-pipe, the Potential Energy is high and the Kinetic Energy is low. When the skateboarder comes down, and get's right around the middle of the half-pipe, the Kinetic Energy is high, and the Potential Energy is low. Through all of that the Mechanical Energy stays the same.

I hope this helps. :)
