Levers and Balance

Posted on January 1, 2011 by Arbor Scientific

In the first lab, students will investigate the arrangements of weights that result in equilibrium (balance) in the lever system. They will find that both the force and the distance from the fulcrum are important in evaluating the system. This investigation leads naturally into a study of torque. In the next three labs, students will [...]

Equilibrium and Torque

Posted on January 1, 2011 by Arbor Scientific

This lab has two activities. In the first, students investigate the arrangement of masses on a center-pivot lever required to produce balance. They will develop the idea that both force and lever arm produce torque, and that both quantities must be considered when trying to produce equilibrium.

The Real Simple Motor

Posted on January 1, 2008 by Arbor Scientific

This simple Homopolar Motor shows how moving charges (an electric current) experience a force when they move through a magnetic field. When the wire is in place, current flows from the battery’s positive terminal, through the wire, radially through the magnet, and into the battery’s negative terminal.
