Answer to Question #91759 in Mechanics | Relativity for Shivangi

Question

We know that Kinetic energy is directly proportional to the square of velocity
And square of velocity is inversely proportional to mass. Therefore, shouldn't the mass be inversely proportional to kinetic energy?

Answer 1

The first statement is true only for small - in comparison with the speed of light - speeds, the second is true only for the square of the speed of light, if the numerator is the total energy of the particle.

Of these two statements, true in the conditions noted above, a third is combined, incorrect.

With this approach, you can think of a lot of things. for example: if you rock like a fan, there will be a breeze, with the wind the trees sway, then the wind arises from the fact that the trees are swinging.
