Question

show that the motion of a
Simple pendulum is a
Simple harmonic motion
And derive time period

Answer 1

Answer:

Let the pendulum is drawn to a side by a small angle ′θ′ and allowed free to oscillatioate in the veritcle plane. Then it will oscillate between the extreme position A and B with a displacement say 'X' at any given time. Let the bob is at onc extreme position say B. The force vertically acting downwards is weight W=mg.
