Water turbines convert the motion of moving water into rotating mechanical energy by catching the water with large blades. They are important to the structure and function of hydropower plants. There are different models... More »

Water turbines produce electricity from kinetic energy by using the force of falling water to stimulate an electric generator. There are two types of water turbines: impulse turbines and reaction turbines. According to t... More »

An impulse turbine, the most common type of small water turbine, works by using a pressurized water jet to turn a wheel called a runner. The runner then turns a shaft attached to the alternator or generator that generate... 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 »

The work-energy theorem is a generalized description of motion that states that the work done by the sum of all forces acting on an object is equal to the change in that object's kinetic energy. This principle of work an... More »

Because any moving thing or object has kinetic energy, there are many examples of this energy type, including a ball dropping into water, a car in motion and a moving arrow. However, there are different types or forms of... More »
