What does T represent in mc^2 equation?

In summary, The equation T = mc^2 - m0c^2 represents kinetic energy and is commonly used in Classical Mechanics textbooks. Some books use T for kinetic energy, while others use different conventions such as K. This equation is also known as Einstein's formula for the energy obtained from converting mass into energy through a nuclear reaction, with c representing the speed of light. The use of T for kinetic energy is not universal and may vary depending on the textbook.

I have an equation which states;

T = mc^2 - m0c^2

I know kinetic energy equals this same equation. Does T also represent kinetic energy in this equation? If so, why has the letter T been used?

Thanks

Some books use T for kinetic and U for potential energy, whereas other books use different conventions.

Is there any particular reason for the letter T?

Does it represent translational kinetic energy?

Kinetic energy is E = ½mv² and may be called by other letters, but E = mc² could only be Einstein's formula for the energy obtained from converting mass m into energy in some kind of nuclear reaction. Here c is the speed of light. I have never seen it called T. Sounds like a misprint.

It's very common for Classical Mechanics textbooks to use the upper case letter T for kinetic energy.

Well that's new ... I've normally have seen K for that

But again i haven't read too many books
