Doubling only the mass of a vibrating mass-and-spring system produces what effect on the system's mechanical energy?
A) increases the energy by a factor of square root of two
B) increases the energy by a factor of two
C) increases the energy by a factor of three
D) increases the energy by a factor of four
E) produces no change

Question

Quizplus · Accepted Answer

The mechanical energy of a mass-and-spring system is determined by the spring constant and the amplitude of the vibration, not the mass. Doubling the mass does not affect the system's mechanical energy.
