A body executes simple harmonic motion. ...

A body executes simple harmonic motion. The potential energy (PE) , the energy (KE) and total energy (TE) are measured as a function of displacement . Which of the following statements is true

A

KE is maximum when `x = 0`

B

`TE` is zero, when `x = 0`

C

`KE` is maximum when `x` is maximum

D

`PE` is maximum when `x = 0`

Text Solution

Verified by Experts

The correct Answer is:
A
A harmonic oscillator crosses the mean position with maximum speed hence kinetic energy is maximum at mean position (i.e. `x = 0`)
Total energy of the harmonic oscillator is a constant.
PE is maximum at the extreme position.
