Reviewing Centrapetal Force and Circular Motion

The video tutorial explores circular motion, highlighting examples from human-made and natural objects. It explains centripetal force as the net force pulling objects towards the center of a circular path, and centripetal acceleration, which depends on speed and radius. The tutorial discusses the balance between centripetal and tangential acceleration, leading to uniform or non-uniform motion. It concludes with an examination of planetary orbits, which are elliptical due to gravitational interactions.

Describe how uniform acceleration is represented on a graph of velocity over time.

What causes planets to have non-uniform centripetal acceleration as they orbit the sun?
