Chapter 4: Rotaional and Circular Motion

Rotational motion is an important part of everyday life. The rotation of the Earth creates the cycle of day and night, and the rotation of wheels enables easy vehicular motion. 

Rotational motion, when combined with Newton’s law of universal gravitation and his laws of motion, can also explain certain facts about space travel and satellite motion, such as where to place a satellite so it will remain fixed in position over the same spot on the Earth
