You forgot to mention, that the equation is only valid for ideal gases. In this case the thermal energy is proportional to temperature times Boltzman constant. This would not justify to call temperature 'energy'. Thermal energy in motion is called 'heat'. Thermal energy in a certain material object is not well defined. See here: https://en.wikipedia.org/wiki/Thermal_energy "In thermodynamics, thermal energy refers to the internal energy present in a system due to its temperature.[1] The concept is not well-defined or broadly accepted in physics or thermodynamics, because the internal energy can be changed without changing the temperature, and there is no way to distinguish which part of the internal energy is "thermal". Instead, the appropriate thermodynamic concept is heat, defined as a transfer of energy (just as work is another type of transfer of energy)." >>>> Mass and energy are not the same thing, hence have different units (kg >>>> and Nm) and those units do not represent the same concept. >>> >>> They do when related by velocity squared.

You have to exchange mass for velocity, if you want to reach c. In the final case of v=c you have m=0, what makes the equation pointless. Actually it is wrong, since light mas energy, but no mass. >> This velocity is also 'relative', since it depends in respect to which >> base-point you measure v. > > Yes, v is relative velocity. C is also relative velocity.

If a fly hits the wind screen of a truck, you would not calculate the kinetic energy of the fly in relation to that of a truck. You can do that, if you insist. But the energy is irrelevant, since it's not the energy of the fly that kills her. TH
