Focuses on an experiment which was conducted to describe relative motion and Coriolis force. Details on the experiment; Information on Coriolis force; Indepth look at apparatus used to conduct the experiment.

Describes a physics activity which illustrates the effect of the Coriolis force on the human arm. Investigation of the cause of the force; Explanation on the occurrence of the phenomenon depending on the rotation of the arm; Other ways to demonstrate the force.

Discusses two applications found in introductory texts and includes some dynamics that clarify motion without any force. Reasons a rock whirling at the end of a string speed up when it is pulled in; Force which speeds up the spinning skater when she brings her arms to the side.

Offers several tips on alternating current circuit measurements. Details on power strips used to measure alternative current; Way to get a voltage measurement; How to measure currents across a shunt.

Corrects a common college physics textbook error in which the behavior of a pulse in a string when it exerts force on the fixed end is not adequately described. Pulse reflection; Relationship with other common wave motions on a string.
