Doubling only the spring constant 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 he energy by a factor of four
E) produces no change

Question

Quizplus · Accepted Answer

The mechanical energy of a mass-and-spring system is proportional to the spring constant. Doubling the spring constant doubles the mechanical energy.
