In the following tutorial, students will learn about the law of conservation of energy. They will read about some of the many forms of energy. They will understand the definition of efficiency of an energy conversion process as the...

Instructional module focusing on energy. Discussion includes forms of energy, conservation of energy, and the laws of thermodynamics. Site also includes an interactive practice quiz and links relating to the topic.

An interactive simulation that teaches about periodic motion, simple harmonic motion, and conservation of energy. Observe one or two pendulums to determine how the swing is influenced by the length of the string, the mass of the pendulum...

The lesson will first explore the concept of current in electrical circuits. Current will be defined as the flow of electrons. Photovoltaic (PV) cell properties will then be introduced. This will lead to the principle of "Conservation of...

From a chapter on work and energy in a Physics textbook. This section of the chapter covers the difference between renewable and nonrenewable energy resources, the growth in the world's energy consumption, and the link between energy use...

[Free Registration/Login may be required to access all resource tools.] Using the law of conservation of energy as a starting off point, students use the specific heat equation to perform calculations that relate mass, specific heat,...

This site provides a set of four Physics problems dealing with the conservation of momentum principle.

Find out about the essential role energy plays in cell function and in sustaining life. Trace energy transformations as they pass from one living thing to another.

This instructional activity explores the drag force on airplanes. The students will be introduced to the concept of conservation of energy and how it relates to drag. Students will explore the relationship between drag and the shape,...

[Free Registration/Login may be required to access all resource tools.] Students explore the different forms of energy and investigate how the law of conservation of energy plays an important part of those forms.

Find out how gravitational potential energy is converted to kinetic energy, then finally into low-grade thermal energy.

See how Earth's temperature would change if the Sun's brightness increased or dimmed or if Earth's albedo was different.

A collection of video lectures from a fundamentals of physics course taught at Yale University. The course is an introduction to physics and discusses Newtonian mechanics, special relativity, gravity, thermodynamics, and waves. Course...
