Question

Show that the motion of a simple pendulum is simple harmonic and hence derive an equation for its time period. What is seconds pendulum?​

Answer 1

Explanation:

Simple pendulum executing simple harmonic motion: Let the mass of the bob is m, and L is the length to which it is suspended from a rigid support. ... Since the restoring force is directly proportional to the negative of the displacement, hence the motion of the simple pendulum is simple harmonic in nature (SHM).
