Q.Is/are there any other way/ways to start the oscillations of a pendulum? Which energy is supplied in this case/cases?

Instead of displacing the bob and releasing it, you can start the pendulum by giving the bob a sharp push (a tap) while it is at the mean position. …

Instead of displacing the bob and releasing it, you can start the pendulum by giving the bob a sharp push (a tap) while it is at the mean position. This supplies kinetic energy directly to the bob, which then swings up and sets the oscillation going. So the oscillation can be started either by supplying potential energy (displac …
