Mechanical Energy Conservation – Work Energy Theorem. ●When only Conservative forces act on an object (Fg, Fsp, Fn) the Mechanical Energy of that object must be conserved: ME = ME at any two points in the problem. Changes in KE or PE must simply transfer from one to another. The work done in the pro ...

The first term under the quadratic is about 1000 times smaller than the second term, indicating that the problem could have been approximated by not even including gravitational PE for the final position. If that approximation would have been made, the result would have been found by taking the nega ...
