The Physics To Go website will be unavailable Friday evening through Saturday afternoon as electrical work occurs in the American Center of Physics server room. Down time will begin at 6PM Eastern Time on Friday. Service is expected to resume by 6PM on Saturday, July 30.

Circulation Motion and Centripetal Force Feature Summary

Physics in Your World
Circular Motion
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.
