Question

Show that the motion of a simple pendulum is simple Harmonic and hence derive an equation for its time period What is second pendulum Calculate the change in the length of simple pendulum of length 1 meter when it's period of oscillation changes from 2 sec to 1.5 sec ​

Answer 1

Answer:

simple pendulum has a small-diameter bob and a string that has a very small mass but is strong enough not to stretch appreciably. The linear displacement from equilibrium is s, the length of the arc. Also shown are the forces on the bob, which result in a net force of −mg sinθ toward the equilibrium position—that is, a restoring force.
