In SHM the restoring force is F = −kx, where k is force constant, x is displacement and a is amplitude of motion. Then total energy depends upon:

Question

G1 Physics · Accepted Answer

Step 1: The mechanical energy of a simple harmonic oscillator is E = K + U and remains constant. Step 2: At a turning point, x = a and velocity = 0, so E = Uₘₐₓ = ½ka². Step 3: For fixed k and a, energy does not explicitly depend on mass m or instantaneous displacement x. Step 4: Hence it depends on k and a. Final answer: (C) k, a.
