Circulation Motion and Centripetal Force Feature Summary

Type:
Physics in Your World
Title:
Circular Motion
Description:
The wake in this image shows that the water-skier, Irish champion Rodney Watson, is moving in a curved path (high-res version). The tension in the tow line and the force of the water on his skis provide the centripetal (inward) acceleration to produce this curve. To find out how the centripetal acceleration depends on the radius and the period for circular motion, visit this Circular Motion Simulation.
