The Physics Education Group at the University of Washington has been investigating student difficulties in drawing and interpreting graphs of moving objects. In the study reported here, students observe an actual motion...

This website consists of a collection of short videos designed for computer analysis in introductory physics classrooms. The videos are 20-40 photograph frames in length and each depict a physical process commonly...

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...
