Resistance is not futile, it is voltage divided by current. The presentation goes in depth covering electric charges, conductors, insulators, electric fields, static charges, and circuits. The lesson is the 12th in a series of 26.

This physics PowerPoint defines the concepts of motion and force. The slideshow consists of an explanation on how motion and force work and give students the chance to demonstrate motion and force through an experiment. The directions...

What would you be if you were attached to another object by an inclined plane wrapped helically around an axis? In this fourth presentation that covers work and simple machines, young physicists look at Newtons and Joules as...

Beginning with definitions of mass and foce, this excellent set of slides summarizes Newton's Laws of motion and universal bravitaions. Components of each law are explained along with examples and questions to inspire discussion. This is...

Explains what static and kinetic friction are and discusses the coefficient of friction for different situations. Presents two simple lab experiments and real-life examples of friction in action.
