	Mechanical energy - Wikipedia, the free encyclopedia
		Mechanical energy includes things like the kinetic energy of a moving billiard ball, or the potential energy a roller coaster at the top of its track.
		Mechanical energy can be transferred from the molecules of a solid to the molecules of a liquid when, for example, a glass of water is stirred.
		Both mechanical energy and mechanical work are measured in the same units as energy in general.

		Mechanical energy is the energy which is possessed by an object due to its motion or its stored energy of position.
		Mechanical energy can be either kinetic energy (energy of motion) or potential energy (stored energy of position).
		Because of the springs have mechanical energy (in the form of elastic potential energy), it is able to do work on the dart.

	A Proposal for a new Renewable Energy Source: the Atmospheric Vortex Engine \| EnergyBulletin.net \| Peak Oil News ...
		Mechanical energy is produced when heat is carried upward by convection because the work of expansion of a heated gas is greater than the heat required to compress the same gas back to its original pressure after it has been cooled.
		The total mechanical energy that could be produced in the atmosphere is 12000 TW whereas the total work produced by humans is 2 TW.
		The energy produced per unit area of turbine would be higher than in conventional wind turbines because the differential pressure across the turbine is much higher since the air is forced to go through the turbines.

		Mechanical energy is energy of motion or of potential for motion on a macroscopic scale.
		One way to think about it is in terms of energy: When the Slinky was just sitting about minding its own business, it was in its equilibrium position, which just means it was sitting still, not twisting on its own.
		When all of the mechanical energy has been converted to heat, the Slinky stops moving, and is back in its original state, with one difference: it's hotter!
