Some energy is changed into the desired form. The rest is changed into undesired form such as heat, light, sound, etc.

potential energy is the form of energy
Some of the energy used to overcome friction is converted into heat due to the resistance between surfaces. This heat energy is typically considered wasted since it is not used to perform useful work.
energy is that which can not be destroyed. it can only be changed from one form to another.
no it says in the law of conservation of energy, energy can not be created or destroyed only changed, but you may loose energy as a different form but you wont gain any
hydrogen
Energy can not be destroyed, so the total amount of energy before a change is equal to the amount of energy after the change. However, some energy is changed into a useful form, but some may be wasted and not used. For example, a light bulb, changes electrical energy into light energy, but some of the energy is changed to heat and some to sound, these are not useful and are wasted, but are changed nonetheless. So a transformation from mechanical energy to heat will have the same total energy at the start as at the finish, but unless it is 100% efficient some of the original energy will be 'lost'
Examples of energy being changed from one form to another include: solar energy being converted to electricity through solar panels, chemical energy in food being converted to mechanical energy in our muscles, and electrical energy being converted to light and heat in a lightbulb.
Yes. Look up the law of conservation of energy.
efficent
Energy cannot be created or destroyed. The energy just changed from one form to another for of energy.
Changing energy involves converting energy from one form to another. This can be done through processes like chemical reactions, electrical circuits, or mechanical activities. Energy can be transformed between potential energy (stored energy) and kinetic energy (energy of motion) in various ways.
