Ever wonder why Earth spins?

Have you ever wonder why Earth spins on its axis and completes a revolution every day? Is there any force that keeps Earth spinning? Is that because of  Gravity or any Magnetic force?

Check out this video to learn why Earth spins and the basics of physics behind the magic

If you find that above video is in simple English and it’s not convincing physicist inside you, lets hear from a NASA scientist in the embedded video. A NASA scientist explains how Earth rotation has started, how fast it was billions of years ago and what caused it to slow down to 24 hours to complete a revolution
