we say that energy can neither be created nor be destroyed so if it can not be created ,  then from where the energy comes

Expert Answer:

- It is a universal fact that energy can neither be created nor be destroyed, it can only be converted from one form to another.
- A simple example is the working of Motor.
- A motor is a device that converts electrical energy into mechanical energy, but this electrical energy is further obtained by applying potential difference and converting chemical  energy of certain electrons into an electrical energy.
- The chemical energy is further a result of atomic and sub atomic energies that the electrons and electrical charges hold.
- Moving ahead,
 The electrical energy is used to transform the coil into magnet, and the interaction of magnetic field is used to convert it into a mechanical force.  
- Thus gaining mechanical movement from the electrical energy.
Therefore, the source and the end point of energy can be understood by comparing it with a circle, having no point of origin and no point of termination.
What is obvious is that every energy is a result of transformation from an another type of energy.
