In this unit, students will discover the period of time of one oscillation, the frequency of oscillation, the object displacement, its velocity, and its acceleration. They will also discover how to apply the principles of conservation of...

After downloading the "Motion Video Analysis" software, users can collect data about moving object's position from digital movie clips. This collection of data will allow them to plot motion graphs and draw conclusions about physics in...

This physics tutorial aims to model and predict not the motion of just one object, but rather what happens when two or more objects collide. The concept of momentum will be the main focus of this module.

Manipulate the mass of a weight and the length of string in this interactive pendulum simulation. Change the speed, friction, and gravity to make the pendulum swing change as measurements are displayed on the screen. Younger students can...

Hermann Ludwig Ferdinand von Helmholtz (August 31, 1821 - September 8, 1894) was a German physician and physicist who made significant contributions to several widely varied areas of modern science. In physiology and physiological...
