A student calculates the momentum of a body moving at a relativistic speed by multiplying the rest mass by the velocity. This gives a result for the momentum that is
A) too large.
B) correct.
C) too small.

Question

Quizplus · Accepted Answer

At relativistic speeds, the momentum should be calculated using the relativistic momentum formula, which includes the Lorentz factor. Simply multiplying rest mass by velocity underestimates the momentum.
