The variation of kinetic energy K with displacement x for a particle in SHM, from mean position x = 0 to extreme position x = A, is represented by: Image

G1 Physics · Accepted Answer

For SHM, total energy E = (1/2)kA² and potential energy U = (1/2)kx². K = E − U = (1/2)k(A² − x²). Hence K decreases parabolically from its maximum at x=0 to zero at x=A.
