Answer this writing prompt! be sure to include the law of conservation of energy, where the energy was lost on the half pipe, and why others were able to get to the top. use words like displacement, distance, and velocity. 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!
