How Does Temperature Relate to Kinetic Energy?

Kinetic energy depends on the mass and velocity of the body in motion, with the velocity contributing more to the overall kinetic energy of the body. Thus, the higher the mass and velocity of a body, the greater the kinetic energy attained. Kinetic Energy (K.E) = …

How Does Temperature Relate to Kinetic Energy?

The change in potential energy, ΔPE, is crucial, since the work done by a conservative force is the negative of the change in potential energy; that is, W = –ΔPE. For example, work W done to accelerate a positive charge from rest is positive and results from a loss in PE, or a negative ΔPE.

Kinetic Energy Calculator

I know that kinetic energy is supposed to change when I change the frame of reference. But I understand that then there must be some other kind of energy to make up for it so that the energy in the system stays unchanged. But I don't see any other kind of energy here. I only see two total energies of the same system that seem to be different.
