1)Can you list other examples of motion,besides those given here?​

Answer 1

Answer:

Let's imagine you have an iron hammer and you want to use it to drive a nail into a piece of wood on the floor.

The iron hammer on its own has no kinetic energy, but it has some potential energy (because of its weight).

To do the work (i.e. drive the nail into the piece of wood), you first have to lift the hammer up – this increases the potential energy of the hammer because of its high position (see Gravitational Energy).

Next, you have to use force to move it down at great speed to hit
