Question

why does velocity of an electron not depend on its mass?
Please explain
Class 11 Physics

Answer 1

Answer:

Explanation:

The inertia (resistance to acceleration) increases, and the object's tendency to curve space around it increases as it's velocity approaches the speed of light. But physicists have found it cumbersome to treat mass as a variable, or to keep saying "rest mass" all the time, so we say that the mass-proper stays the same.
