  2. Mechanical energy - Wikipedia

    en.wikipedia.org/wiki/Mechanical_energy

    A generator converts mechanical energy into electrical energy. [19] A hydroelectric powerplant converts the mechanical energy of water in a storage dam into electrical energy. [20] An internal combustion engine is a heat engine that obtains mechanical energy from chemical energy by burning fuel. From this mechanical energy, the internal ...

    Wind energy is the kinetic energy of air in motion; Wind power is the conversion of wind energy into a useful form of energy, such as using wind turbines to make electricity, windmills for mechanical power, windpumps for water pumping or drainage, or sails to propel ships

  4. Specific mechanical energy - Wikipedia

    en.wikipedia.org/wiki/Specific_mechanical_energy

    Specific mechanical energy is the mechanical energy of an object per unit of mass. Similar to mechanical energy, the specific mechanical energy of an object in an isolated system subject only to conservative forces will remain constant. It is defined as: = k + p. where

    For instance, in Newtonian mechanics, the kinetic energy of a free particle is E = ⁠ 1 / 2 ⁠ mv 2, whereas in relativistic mechanics, it is E = (γ − 1)mc 2 (where γ is the Lorentz factor; this formula reduces to the Newtonian expression in the low energy limit).
