In the following interactive students will begin to explain work as a transfer of energy and net work as the work done by the net force. They will also explain and apply the work-energy theorem.

In the following interactive students will define conservative force, potential energy, and mechanical energy. They will explain the potential energy of a spring in terms of its compression when Hooke's Law applies. Students will also...

Through interactive practice problems and examples, students calculate the amount of work done by forces.

This site is from the Physics Department at Georgia State University. The conservation of energy as a fundamental conservation law is presented and compared to other conservation laws (momentum and angular momentum). Links to further...

This site is from the Physics Department at Georgia State University. The reliance upon the law of conservation of energy as an approach to problem-solving is presented and encouraged. It is modeled through a problem involving a...

The orbits of satellites are described and an energy analysis is performed. Kinetic, potential and total mechanical energy are explained and applied to the motion of satellites.

African American convicts faced physical abuse, were forced to work long hours, and experienced poor living conditions as part of the "Convict Lease" program set up to pay for the prison system. Read about why this program was started...
