A particle is executing simple harmonic motion with a time period T. At time t=0, it is at its position of equilibrium. The kinetic energy - time graph of the particle will look like :
As we learned,
The total energy in S.H.M. -
Total Energy = Kinetic + Potential Energy
- wherein
Total Energy =
Hence total energy in S.H.M. is constant
At mean position t = 0, , y = 0
At extreme position
K.E. in S.H.M. = K.E.
