Not quite. The battery stores the energy, in the form of chemical energy.
When you're ready to use the energy, it leaves the battery in the form of
electrical energy. Then, if you feel like it, you can use the electrical energy
to run a fan or a motor, which converts it to mechanical energy.
no
Gravitational potential energy in the water is converted into mechanical energy by turning turbine "blades", the mechanical energy (kinetic energy) is converted to electrical energy by the electric generator.
The most familiar example of this is running an electric motor.
Through an electromagnet- most commonly when the electromagnets are part of an electric motor.
The principle of mass conversion to energy. The mass loss (due to nuclear fission or nuclear fusion) is converted to thermal energy. The thermal energy is converted (through turbines) to mechanical energy. The mechanical energy is converted (through electric generators) to electrical energy.
no
The chemical energy is initially converted to electrical energy. This electrical energy works its way through a motor and is converted to mechanical energy.
Mechanical energy
energy is never lost. It is either converted from one form of energy to another (from heat to mechanical, from mechanical to electric, from electric to heat).
Electrical energy, converted to mechanical energy by an electric motor.

The correct answer is Electric motor. An electric motor is a device used to convert electricity into mechanical energy whereas an electric generator converts mechanical energy into electrical energy.
Through an electromagnet- most commonly when the electromagnets are part of an electric motor.
The principle of mass conversion to energy. The mass loss (due to nuclear fission or nuclear fusion) is converted to thermal energy. The thermal energy is converted (through turbines) to mechanical energy. The mechanical energy is converted (through electric generators) to electrical energy.
Assume no vibration loss, the amount of energy input to electric motor subtract out the converted 92 J of mechanical energy is the thermal energy produced.
