Circular Motion: Understanding the Forces that Drive It

The video tutorial explores why objects move in circular paths, using the moon's orbit around the earth as an example. It explains that gravitational force acts as a centripetal force, keeping the moon in orbit. A general diagram of circular motion is presented, highlighting centripetal force, velocity, and orbit radius. Examples of circular motion in everyday life, such as cars on roundabouts and hammer throws, are discussed. The video concludes by explaining the effect of removing centripetal force, causing objects to move tangentially.
