What is Rotation and Revolution?

Rotation is defined as the circular movement of an object around the center of rotation. For instance, as you know planets like Earth and also Moon rotate around an imaginary axis, called the rotational axis, which is the reason why we experience day and night. However, one thing we must remember is that if the said axis is passing through the center of mass, then the said body is said to be spinning on itself, instead of around another body. Although revolution is similar to that of rotation, instead of rotation around its axis, under this principle, the body rotates around another body. For instance, as you know, the planets revolution around the sun, and the moon revolution around the earth. Enroll now at Tutoroot.
