An electron is moving at 0.6c.If we calculate its kinetic energy using (1/2)mv², we get a result which is: A)just right B)just half enough C)twice the correct value D)about 1% too low E)about 28% too low

Question

Quizplus · Accepted Answer

The classical kinetic energy formula (1/2)mv^2 does not account for relativistic effects, which become significant at speeds close to the speed of light. At 0.6c, the relativistic kinetic energy is about 28% higher than the classical calculation.
