How long did it take to develop the first life forms?

The earliest time that life forms first appeared on Earth is at least 3.77 billion years ago, possibly as early as 4.28 billion years, or even 4.5 billion years; not long after the oceans formed 4.41 billion years ago, and after the formation of the Earth 4.54 billion years ago.

Explanation:

1. potential energy is attributed to mass and position while kinetic energy is attributed to mass and speed.

3. in electric energy electricity involves motion of electrons and they do have kinetic energy. that is why electric energy can be regarded as a form of kinetic energy.
