this thing has been bothering me for a long time
what I had in mind was this situation:
If we throw a rock from the ground to the top of a building then it's kinetic energy has clearly increased but it just stays on the roof of the building so the increase in kinetic energy has become...
Maybe we should view the situation in this way?
since the object was moved a certain distance by a force work was done on it so its kinetic energy has increased but since it stays at that height the kinetic energy becomes potential energy?
