Write the expressions for potential and kinetic energy ofa bodyexecuting simple harmonic motion |
| Answer» TION:purely KINETIC. At the MEAN position, the velocity of the particle in S.H.M. is maximum and displacement is minimum, that is, x=0. Therefore, P.E. =1/2 K x2 = 0 and K.E. = 1/2 k ( a2 – x2) = 1/2 k ( a2 – o2) = 1/2 KA2. Thus, the total energy in simple harmonic MOTION is purely kinetic. | |
