Document Summary

There are a lot of types of potential energy, but right now we are only discussing one- which is potential energy due to gravity. For an isolated system, energy is conserved. Energy cannot be created or destroyed, just changed. K f + u f = k i + u i. Work is defined as the force in the direction of motion multiplied by the distance moved. Initial energy plus work equals final energy. Example 1 - a circus performer jumps from a tower into a bucket of water. She has 10,000 j of energy at the top. Energy at the top is the same as the energy at the bottom, so the energy does not change. E f therefore equals 10,000 j because e f = e i. U f equals 0 because the height is 0. K f = mv 2 v = m2. , so you cancel the kg and you"re left with m2 s2.
