chemical
An automobile engine converts chemical energy from fuel (such as gasoline) into mechanical energy through combustion. This mechanical energy is used to power the vehicle and drive the wheels.
A generator changes mechanical energy into electrical energy.
The motor changes electrical energy into mechanical (torque) energy.
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.

The body changes chemical energy to mechanical energy to power muscle contractions and movement.
Chemical energy changes to electrical energy which changes into mechanical energy
Chemical energy changes to electrical energy which changes into mechanical energy
Mechanical energy is the sum of an object's kinetic energy (energy due to motion) and potential energy (energy due to its position or state). When an object moves or changes position, its mechanical energy changes to reflect the balance between kinetic and potential energy.
An electromagnet contains a moveable core that changes electrical energy to mechanical energy. By passing an electric current through the coil, the core becomes magnetized, creating movement or mechanical energy.
