Wikipedia provides detailed information on electrical potential, including a definition, introduction, and mathematical formulas.

With an introduction to the ideas of energy, learners discuss specific types of energy and the practical sources of energy. Hands-on activities help them identify types of energy in their surroundings and enhance their understanding of...

Outlines the seven main principles of energy.

An explanation of types of energy, how living things use energy and how they can convert energy forms. This is a good, basic, start to studying this characteristic of life.

This activity will provide students with a qualitative understanding of the Work-Energy Theorem, especially on how the energy transferred depends on the distance over which the force is applied.

This activity is based on the common experiment of running a marble down a ramp to do work on a cup. Students will be able to see the relationship between mass and energy of the marble and the ramp height.

Students must find how much energy has been added to a spring by looking at the Force vs. Spring Length graph.

Explore distance and energy of bond formation.

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

Demonstrates how principles of kinetic energy, potential energy and energy conservation can be used to determine the speed of a descending object if given its initial height. Further discussion of other topics such as heat and...

A site dedicated to help students prepare for the AP Physics B test. This specific site reviews work and energy including work-energy theorem, conservation of energy, potential energy and power. Site contains links to video lectures and...

Kids learn about kinetic energy in the science of physics. The energy of motion can be calculated using mass and velocity. The standard unit is the joule. How it is different from potential energy.

This site from the Georgia State University explains the concept of electric potential about a point charge or combination of severat point charges. An interactive JavaScript form allows the visitor to investigate the effect of distance...

A series of pages which define key terms and explain basic concepts related to electric potential. Includes a set of practice problems with answers and solutions.

Discusses electric forces, electric fields, electric potential, and the role that electric potential plays in enabling materials to pass through a cell membrane.

Texas has the potential for becoming a leading provider of biomass energy due to its agricultural industry. Some crops produced in Texas, such as canola, switchgrass, sorghum, and sugarcane, have been identified as energy crops that...

Water creates a lot of energy, just look at the Grand Canyon. In this science fair project, you will demonstrate the power of water by converting the kinetic energy in moving water to mechanical energy, which will lift a small weight.

By the end of this section, you will be able to define nonconservative forces and explain how they affect mechanical energy, and to show how the principle of conservation of energy can be applied by treating the conservative forces in...

An interactive map of the United States that gives information about each state's wind power potential.

Activity 1 of this module investigates: How does potential energy change when things are pushed or pulled? Exploring how force is related to potential energy, this activity investigates how potential energy is changed when a spring is...

In this module Activity 3 investigates When atoms get close to each other, what happens to their potential energy? This activity applies energy concepts to compare the potential energy of atoms that are bonded as molecules with the...

Read about all the different kinds of potential and kinetic energy. Includes energy formulas and examples of energy applications.

Using a roller coaster as an example, the transformation of mechanical energy from the form of potential to the form of kinetic and vice versa is explained and illustrated in the animation.

The energy in the universe never increases or decreases- but it does move around a lot. Energy can be potential or kinetic. George Zaidan and Charles Morton get excited about energy. [3:52]
