Physics stars will enjoy learning about the conservation of energy as you demonstrate gyroscope precession. The lecture is broken into five subtopics: cross product, rotating vectors, angular momentum, rotating rigid bodies, and torque...

Students discuss that the conservatin of energy states that the energy imput must equal the energy output. They then figure out how can a machine help you to perform task otherwise considered impossible? Students discuss the six simple...

Torque--a teachable moment? Here's a lesson on torque (or moment) and variables that include size, reinforcement, structural bracing, and material that affect torque.

Students explore questions which cannot be handled with simple pendulums, and examine both the usefulness and the limitations of approximations in science. A Java applet created from a Stella model is included.

Students listen to a lecture by the teacher about farm work and ways to use physics to make farm work easier. The machines that are highlighted include pulleys, ramps, lever, and gears. Each machine is explained in context of its use in...

Students solve vector problems and identify the x and y coordinates. They determine if the coordinates are positive, negative, or zero. Students solve problems and convert the x and y coordinates to magnitude and direction.

Students explain necessity in using accurate instruments when measuring, and how measurements can be checked for accuracy. They make a six-inch ruler, design, test, and evaluate a system to measure work, and produce a table and graph to...

This study guide on circular motion covers key terms, centripetal force, linear vs. circular motion, precession, and equations. Includes four example problems with detailed solutions. The guide is available for download with free...

Determine the unknown mass that is being balanced by a known mass for a meter stick balanced at its center of mass (50.0 cm mark).

Determine the mass of a meter stick that is being balanced by a known mass. The center of mass for the meter stick is located at the 50.0 cm mark.
