Physiclips thoroughly presents mechanics concepts with animations and film clips.

This site from the University of Evansville contains information on the centroid. The information is brief and two picture images are given as well.

Determine the unknown mass that is being balanced by two known masses for a meter stick balanced at its center of mass (50.0 cm mark).

Students defy gravity by stacking blocks in different ways in this exercise. Other projects are linked to this lesson as well.

In this Science-athon, students try to make their marble roll the farthest across a flat surface, using their knowledge of forces, motion, and energy to guide them through their apparatus design. Teachers must enroll online.

Includes exhaustive information and a wealth of activities pertaining to aerodynamics and the physics of flight.

A map from 1904 of the eastern United States showing the westward progression of the centers of population from 1790 to 1900. "The centre of population is defined as 'the point at which equilibrium would be reached were the country taken...

Through ten lessons and numerous activities, students explore the natural universal rules engineers and physicists use to understand how things move and stay still. Together, these rules are called "mechanics." The study of mechanics is...
