"A pendulum is released from a height of h metres. At the equilibrium point the resultant force on the pendulum is zero. Explain why the pendulum continues to oscillate in spite of this" [3 marks]
The Attempt at a Solution
So I presume that it had something to do with the inertia of the pendulum (i.e: newtons first law). But I don't know how to correctly phrase the 3-mark answer. Could someone please help.
