Authored by Eleanor Kopsian of Franklin Frazier, this is an activity intended to help students understand orbital motion and Kepler's Laws through a comparison of a circle and an ellipse and the application of Kepler's...

Simply in design, this lesson plan was created by Deborah Lojkutz of Joliet West High School, the objective of this activity is to teach students the concept of periodic motion and relate it to the movement of a...

This webpage contains an applet that simulates the control of a Lunar Lander. The user is must touch down gently on the lunar surface. Key commands control the thrust and the orientation of the Lander. Extra points for...

This simulation provides a realistic virtual mass-and-spring laboratory. Users can explore spring motion by manipulating stiffness of the spring and mass of the hanging weight. Concepts of Hooke's Law and elastic...

This webpage contains a simulation that shows simultaneous graphs of position, velocity, and acceleration of a moving object. A simulated man can be moved by the user, or the motion can be programmed by setting the...
