a device to convert energy into useful mechanical motion

Conservation of Energy | Physics

Nuclear energy comes from processes that convert measurable amounts of mass into energy. Nuclear energy is transformed into the energy of sunlight, into electrical energy in power plants, and into the energy of the heat transfer and blast in weapons. Atoms and molecules inside all objects are in random motion.

Triboelectric Nanogenerators as New Energy Technology for ...

Sep 30, 2013· Triboelectrification is an effect that is known to each and every one probably since ancient Greek time, but it is usually taken as a negative effect and is avoided in many technologies. We have recently invented a triboelectric nanogenerator (TENG) that is used to convert mechanical energy into electricity by a conjunction of triboelectrification and electrostatic induction. As for this power ...

Nanogenerator - Wikipedia

Piezoelectric nanogenerator. A piezoelectric nanogenerator is an energy harvesting device capable of converting external kinetic energy into electrical energy via action by a nano-structured piezoelectric material. Although its definition may include any types of energy harvesting devices using nano-structures to convert various types of ambient energy (e.g. solar power and thermal energy), it ...

The 13 Types of Energy and Their Varied Applications and ...

Numerous modern devices convert other forms into mechanical energy and vice-versa, like thermal power plants (heat to Me), electric generators (Me to electricity), turbine (Kinetic energy to Me), etc. The conservation of mechanical energy is also dependent on whether two bodies experience collision that is either elastic or non-elastic.

Perpetual motion - Wikipedia

Perpetual motion is the motion of bodies that continues forever in an unperturbed system. A perpetual motion machine is a hypothetical machine that can do work infinitely without an external energy source. This kind of machine is impossible, as it would violate the first or second law of thermodynamics.. These laws of thermodynamics apply regardless of the size of the system.

Heat Engines, Entropy, and the Second Law of Thermodynamics

and the high-temperature gases produced are used to convert liquid water to steam. This steam is directed at the blades of a turbine, setting it into rotation. The mechanical energy associated with this rotation is used to drive an electric genera-tor. Another device that can be modeled as a heat engine is the internal combustion

Wave-Motion Gun - TV Tropes

The Cool Ship needs an equally cool weapon. If it''s a sufficiently humongous Cool Ship, it will be equipped with a Laser Beam on steroids: the Wave Motion Gun — an enormous Ray Gun that fires a massive energy beam capable of blowing away an enemy ship (in the "blow a battleship in half" sense), sometimes an entire fleet, with one shot, and maybe even blowing up an entire planet.

Law of Conservation of Energy | Statement & Examples ...

Law of Conservation of Energy in Classical Physics Conservation of Mechanical Energy. First the principle of the Conservation of Mechanical Energy was stated:. The total mechanical energy (defined as the sum of its potential and kinetic energies) of a particle being acted on by only conservative forces is constant.. An isolated system is one in which no external force causes energy changes.

Alternative energy sources presentation

Feb 06, 2016· WAVE POWER Wave energy is produced when electricity generators are placed on the surface of the ocean. Wave power is the transport of energy by ocean surface waves, and the capture of that energy to do useful work. For example, electricity generation, water desalination, or the pumping of water (into reservoirs).

Steam engine - Wikipedia

A steam engine is a heat engine that performs mechanical work using steam as its working fluid.The steam engine uses the force produced by steam pressure to push a piston back and forth inside a cylinder. This pushing force is transformed, by a connecting rod and flywheel, into rotational force for work.The term "steam engine" is generally applied only to reciprocating engines as just ...
