since velocity is always based on a frame of reference, can I just change my frame of reference to have different amounts of kinetic energy? Where does that energy come from?
In: Physics
If velocity, a necessary part of the formula for kinetic energy, is based on a frame of reference…then wouldn’t kinetic energy have to be based on that same frame of reference?
So if you change your frame of reference for velocity to get a different measurement, you have a proportionally equal amount of kinetic energy because it’s based on the same frame of reference.
You aren’t “creating kinetic energy”, you’re changing the frame of reference with regard to kinetic energy.
