This lesson points out that the motion of objects (velocity or acceleration) is almost never constant, and applies this idea to the motion of a person walking. The discussion covers the energy transfers involved in...

This web page, authored and curated by David P. Stern, describes motion of an object traveling in a circle. The need for centripetal force to maintain the object's acceleration is derived using algebra and the Pythagoras...

This simulation displays the motion of a simple harmonic oscillator. The user can adjust the physical parameters in the problem including mass, spring stiffness, and damping. Graphs can be plotted relating any two...

This webpage contains a simulation that allows the user to fire various objects out of a cannon. By manipulating angle, initial speed, mass, and air resistance, concepts of projectile motion are illustrated. This page...

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...
