Question

At what velocity does the K.E of a particle equal its rest energy?

Answer 1

Answer:

The relativistic kinetic energy is the measurement of the kinetic energy of a particle that moves at a velocity that is significant compared to the speed of light. It incorporates both the relativistic mass and the rest energy of the particle.

Answer 2

Answer:

it should be zero because according to the formula KE = 1/2mv^2

where v=0

then the particle comes to rest
