How does the kinetic energy of a proton change when its total energy doubles?
A) It doubles.
B) It more than doubles.
C) It less than doubles.
D) It must increase but it is not possible to say how much.

Question

Quizplus · Accepted Answer

When the total energy of a proton doubles, its kinetic energy more than doubles. This is because the total energy includes both the rest mass energy (which remains constant) and the kinetic energy. Doubling the total energy significantly increases the kinetic energy beyond just doubling it, as the rest mass energy component does not change.
