1. The problem statemees and given/known data
A ball has a potential energy of 200J. Once the ball reached the ground, it's kinetic energy was 175J. Is this possible and does this defy the conservation of energy?
KE = PE
I am not sure. Being in high school, we have always been taught that KE = PE but if PE is 200, how can KE be 175? Where is the other 25J
