A skateboarder, just learning to use a half pipe as shown below, drops in off the top of
one side. She stands straight as she skates down the one side and up the other. She
expected to get to the top of other side but didn't make it. The skateboarder recalled
the law of conservation of energy from science and didn't understand why she didn't
make it to the top of the other side. She then watched some more experienced skaters.
She noticed that they bent their knees and pushed off at the bottom.
Explain why the skateboarder did not make it to the top of the other side of the half
pipe. In your reponse, be sure to include:
the law of conservation of energy
where energy was lost as the skateboard moved across the half pipe.
why the other skaters were able to make it to the top.
