Q. If a simple harmonic oscillator has a total energy E, what is the kinetic energy when the displacement is half of the amplitude?
A.
E/4
B.
E/2
C.
3E/4
D.
E
Solution
The total energy E is conserved. When the displacement is half the amplitude, the potential energy is (1/2)E, so the kinetic energy is E - (1/2)E = (1/2)E.
Q. If the amplitude of a simple harmonic oscillator is doubled, how does the total energy change?
A.
Remains the same
B.
Doubles
C.
Quadruples
D.
Halves
Solution
The total energy in simple harmonic motion is proportional to the square of the amplitude. If amplitude is doubled, energy increases by a factor of 2^2 = 4.

FAQs
Question: What is Simple Harmonic Motion? Answer: Simple Harmonic Motion is a type of periodic motion where an object oscillates around an equilibrium position, characterized by a restoring force proportional to the displacement from that position.
Question: How is energy conserved in SHM? Answer: In Simple Harmonic Motion, energy oscillates between kinetic and potential forms, with the total mechanical energy remaining constant if no external forces act on the system.
