Georgia State University: Hyper Physics: Thin Lens Equation

This site from Georgia State University Physics Department defines and explains the concept of potential energy. Using equations and graphics to illustrate the idea, it discusses the many types of potential energy (gravitational,...

This site from Georgia State University Physics Department defines kinetic energy and compares and contrasts it with other forms of energy. Provides an equation and links to further, more-detailed information.

At this site from Georgia State University Physics Department the operation of a telephoto lens is discussed. The refraction of light through the lens is shown and a link to a calculation page is provided.

This site from Georgia State University Physics Department provides a discussion of how light refracts through the lenses of a microscope. Demonstrates the parts of a microscope and includes an interactive form in which the magnifying...

HyperPhysics is an exploration environment for concepts in physics by Georgia State University which employs concept maps and other linking strategies to facilitate smooth navigation. This section focuses on electricity and magnetism.

Explains what each of the four fundamental forces is and their interactions with the physical world. The four types are the strong force, the weak force, the electromagnetic force, and the gravitational force.

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...

This site from Georgia State University defines electric potential energy and relates it to the concept of electric potential. Discusses the idea of a reference point or a zero potential location.

This informative site is from Georgia State University. The tendency of nature to move towards a more disordered state in an isolated system, a concept known as entropy, is discussed. This concept is well-depicted in meaningful diagrams.
