Elastic energy is the potential energy stored in a material or physical system as the volume or shape is distorted. When objects are stretched or compressed, elastic energy is stored, according to the Physics Classroom. More »

A Venturi pump uses the kinetic energy in a fast-moving fluid to move another liquid or semi-liquid substance. These pumps are abundant in sewage treatment plants because they reliably move large volumes of thick, hetero... More »

Albert Einstein's formula "E=mc2" means energy equals the mass of an object multiplied by the speed of light squared. His theory means that the mass of an object, no matter how small, can be transformed into a tremendous... More »

Actuators depend on transfer of energy – via electricity, hydraulic pressure, human muscle or otherwise – to perform mechanical work that sets a system in motion or controls it. Actuators can be mechanical systems, such ... More »
