The general answer is that energy conversion is the conversion of one type of energy into another. We use this principle all the time every day. For instance, we use chemical energy in a battery to create electrical energy to power an electric starter motor. This motor uses the electrical energy to create mechanical energy to start a vehicle. The vehicle converts chemical energy into mechanical energy to make the vehicle go. If you think about the types of energy, you can come up with all sorts of things that change one type of energy to another type. A microphone converts the mechanical energy of sound into electrical energy. There is a boatload of other examples.
"Conversation of energy" is a good non example of 'conservation of energy'
Energy converting into another energy
catabolism
conversation of energy of electromagnetic
Kinetic energy to electrical energy
Energy cannot be created nor destroyed it can only be moved.
Chemical (gas) to thermal (combustion) to mechanical More Simply: Chemical Energy to Mechanical Energy
It means that, assuming there if no friction, the sum of kinetic energy + potential energy doesn't change.
Kinetic energy converting to gravitational potential energy
law of conservation of energy
gravity
Kinetic energy becoming potential energy.
