This lesson builds upon the previous two (Newton's Second Law and the First Law of Thermodynamics) by explaining that conservation of energy is not perfectly observed, in that energy is lost as it is transferred from...

This site contains various applets and animations of physical processes, demonstrating various ideas in waves, optics, mechanics, and thermodynamics. The site also contains information on the theory behind diffraction...

Freestudy is dedicated to providing free tutorials and resources for those studying engineering from the degree level to certificate level. The site specializes mainly in Mechanical Engineering and provides materials on...

Created by Paul Falstad, this applet simulates kinetic theory of gases. The volume, temperature of a plate at the bottom, and force of gravity are adjustable. A histogram displays relative velocities of different...

This is the second part of a two-part exercise in which students perform an audit and analysis of energy consumption in their homes. In this part, students will estimate the amount of energy they use in their homes and...
