A moving car on the highway has mechanical energy in the form of both kinetic energy (energy of motion) and potential energy (stored energy). A winding clock spring stores potential mechanical energy that is released as kinetic energy when the clock unwinds and moves the gears. A bouncing ball has mechanical energy as it moves between potential energy when it's at the highest point of its bounce, and kinetic energy as it moves back towards the ground.
Nuclear reactions, chemical reactions, and mechanical processes like falling objects releasing potential energy as kinetic energy are examples of processes that release energy.
To calculate mechanical energy, you typically add the kinetic energy (0.5 * mass * velocity^2) to the potential energy (mass * gravity * height). The total mechanical energy is the sum of these two forms of energy.

Kinetic energy of a moving object.

There are many examples of how chemical energy can be transformed into mechanical energy. Perhaps the best known example is the combustion of gasoline in an engine to power an automobile.
An example is pushing a toy car you have to push the car and your moving and the car moves also mechanical energy
Examples of mechanical heat energy include frictional heating produced when rubbing hands together, the heat generated when braking a car, and the heat generated from compressing air in a bicycle pump.

Examples of conversion of mechanical energy into light energy include a light bulb, which converts electrical energy (generated by a mechanical source like a power plant) into light energy through the heating of a filament, and a hand-crank flashlight, which converts mechanical energy from the hand-crank into light energy through the activation of a dynamo or generator.
List of examples of energy conversions1. Electric Generator (Mechanical Energy into Electrical Energy)2. Electric Motor (Electrical Energy into Mechanical Energy)3. Steam Engine (Thermal Energy into Mechanical Energy)4. Diesel or Petrol Engine (Chemical Energy into Mechanical Energy)5. Stove (Chemical Energy into Thermal Energy)6. Electric Bulb (Electrical Energy into Thermal and Light Energy)7. Cellular Respiration (Chemical Energy into Thermal and Mechanical Energy)
Examples of mechanical kinetic energy include a moving car, a revolving ceiling fan, a spinning top, and a swinging pendulum.
The device that converts electrical energy to mechanical energy is an electric motor. Electric motors are also used as generators in hybrid automobiles to convert mechanical energy back to electrical energy.
