Covers the meanings of force, friction, and gravity, and the differences between magnetic and elastic spring force, and between weight and mass. The effect of air resistance on an object's motion is also touched upon.

This lesson begins with an activity in which students induce EMF in a coil of wire using magnetic fields. Then, demonstrations on Eddy currents show how a magnetic field can slow magnets just as Eddy currents are used to slow large...

This instructional activity begins with a demonstration of the deflection of an electron beam. Students then review their knowledge of the cross product and the right hand rule with sample problems. After which, students study the...

This lab was designed to have students figure out the formula for the force on a charge moving through a magnetic field. Then they are to see how the direction of the force is dependent on the direction of the charge's motion and the...

This site offers a wealth of online textbook-related materials that encourage the discovery of science in the world around us. Enter the site to access material on specific topics. Each section contains reading material (complete with...

Simulate the motion of a charged particle in electric and magnetic fields, and then complete the equations of motion using the Lorentz force law.

This site, in German, offers numerous apps that illustrate common physics principles. Apps are organized into categories: mechanics, oscillations and waves, electrodynamics, optics, thermodynamics, the theory of relativity, physics of...

[Free Registration/Login Required] Use this interactive simulation to understand how magnetic forces applied to charges in motion generate circular [centripetal) motion, and how the paths these particles leave provide insight into their...

Link to nine major physics topics and dig deeper into the content. Find out about the work of scientists in each field and see example physical science experiments.

Exploratorium's snacks aren't edible, but they are good! Use your science skills to discover gravity, learn about biology, do fun experiments.

A set of four online courses in Physics for elementary and middle school teachers. Each course targets a different topic area - light, electricity & magnetism, temperature & heat, and force, motion, & energy.
