This is an animation of a simple pendulum.  As the pendulum swings, bar graphs display changes in potential and kinetic energy.

This is an animation displaying two spring oscillators.  Users can view graphs of their motion from three views:  different amplitudes, different frequencies, and different phases.

This is an interactive simulation that illustrates conservation of angular momentum in an orbiting object.

This is an interactive tutorial that simulates orbital motion.  Users can set initial velocity of a small mass orbiting a larger mass and observe the different trajectories produced.  Energy vs. Time graph is included.

This interactive Java simulation depicts a pendulum undergoing two amplitudes of oscillation:  20 degrees and 135 degrees.  It illustrates the simple harmonic motion produced by small amplitudes, compared with the non-sinusoidal nature of large amplitudes.

This is an interactive Java simulation that illustrates the relationship between SHM and uniform circular motion.

This is an interactive Java simulation that illustrates simple harmonic motion graphed as a function of position, velocity, and acceleration.

This is an animation depicting the orbits of the four inner planets of the solar system.  Students can observe each orbital path relative to the others.

This item is an interactive homework problem within this collection relating to two cars.  One car is stopped and will accelerate at a constant rate; the other car is traveling at constant speed.  When will one car overtake the other?

This is an interactive simulation that explores the relationship between displacement and pressure in a sound wave.

This is an interactive homework problem within this collection relating to free fall.  The accompanying animation depicts the motion step-by-step.

In this simulation, students stretch and compress a spring and view a simultaneous Force vs. Position graph that plots the magnitude and direction of the spring force.

This is a simulation of the old amusement park known as The Gravitron.  Riders lined the walls of a large cylinder, which began to accelerate in rotational speed.  Eventually the floor drops away.  What causes the riders to stay "pinned" to the wall?  Why are these rides now commonly outlawed?

This is a simulation designed to help students analyze the forces acting upon an objects such as roller coasters, which travel in vertical circular motion.

In this simulation, a spring stretched to elastic limit is simultaneously graphed in Work vs. Position and Force vs. Position graphs.

This is an interactive simulation within this collection that depicts the relationship between the force and the oscillating mass in a driven oscillator.

This interactive tutorial combines a simulation of a whirligig with step-by-step help in solving a related homework problem.

This interactive homework problem simulates the common physics demonstration involving two objects of identical mass on a rotating horizontal turntable.  A Frictional Force vs. Time graph is depicted simultaneously as the turntable accelerates.

This item is a short tutorial which explains a simple method for calculating the coefficient of static friction.
