Energy cannot be created, it can only change forms. In that case what is the source of tidal energy? What other energy is getting converted here?

Question

I know that it is caused by the Sun and Moon’s gravitational pull. But where is the energy coming from? Who is losing energy?

Is gravity an unlimited energy source?

Answer 1

The movement of the moon relative to the Earth.

Since Earth rotates faster than the moon orbits it, the result is the Earth rotating slower and the moon orbiting faster. Most of the energy of Earth’s lost rotation becomes tidal energy.
