For thousands of years, navigators have looked to the sky for direction. Today, celestial navigation has simply switched from using natural objects to human-created satellites. A constellation of satellites, called the Global Positioning...

[Free Registration/Login may be required to access all resource tools.] Students explore instantaneous velocity and how to calculate it. They also learn how interpret and create position vs time graphs.

Here's a geology project that uses historical seismograph data that you can collect from the comfort of your own computer. You'll use a web interface to a network of seismometers run by the Northern California Earthquake Data Center, at...

Explains what is meant by kinetic energy and demonstrates how to use the formulas for a point mass moving at less than the speed of light, for rotational motion, and for a mass moving at a relativistic speed. Includes interactive...

This activity demonstrates how potential energy (PE) can be converted to kinetic energy (KE) and back again. Given a pendulum height, students calculate and predict how fast the pendulum will swing by understanding conservation of energy...

For this lesson, young scholars are introduced to both potential energy and kinetic energy as forms of mechanical energy. A hands-on activity demonstrates how potential energy can change into kinetic energy by swinging a pendulum,...
