Question

so that the motion of simple pendulum is simple Harmonic Motion also derive the expression for time period​

Answer 1

The motion of Simple Pendulum as Simple Harmonic Motion. ... Therefore, the motion is periodic and oscillatory. Now, if we displace the pendulum by a very small angle Θ, then it performs the simple harmonic motion. Consider a simple pendulum having mass 'm', length L and displaced by a small angle Θ with the vertical.
