I don't see any reason to even consider "energy" as a factor
The kinetic energy of an object is the energy which it possesses due to its motion.[1] It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes. The same amount of work is done by the body in decelerating from its current speed to a state of rest.
The speed, and thus the kinetic energy of a single object is frame-dependent (relative): it can take any non-negative value, by choosing a suitable inertial frame of reference. For example, a bullet passing an observer has kinetic energy in the reference frame of this observer.
The same bullet is stationary from the point of view of an observer moving with the same velocity as the bullet, and so has zero kinetic energy.[2] By contrast, the total kinetic energy of a system of objects cannot be reduced to zero by a suitable choice of the inertial reference frame, unless all the objects have the same velocity.
If a rigid body is rotating about any line through the center of mass then it has rotational kinetic energy which is simply the sum of the kinetic energies of its moving parts, and is thus given by:
