Question

How we can make a pendulum clock? ​

Answer 1

Answer:

You could start with a dial and some hands and move them around the face with your finger, counting seconds to yourself .

Answer 2

Answer:

A pendulum works by converting energy back and forth, a bit like a rollercoaster ride. When the bob is highest (furthest from the ground), it has maximum stored energy (potential energy). ... So as the bob swings (oscillates) back and forth, it repeatedly switches its energy back and forth between potential and kinetic.
