Consider two identical particles (with mass ? 0) undergoing a collision with one at rest. As the speed of the other particle increases, the fraction of its energy available for the creation of new particles
A) increases.
B) remains unchanged.
C) decreases.
D) Insufficient information is given for a response that is valid in general.

Question

Quizplus · Accepted Answer

As the speed of the moving particle increases, more of its energy is in the form of kinetic energy rather than rest energy, leaving less energy available for the creation of new particles.
