I have observed a change in energy but cannot explain it?

The power output is smaller than the power input as most of the energy usually has been converted to heat in the process...

Energy is not "lost" it is converted to a form that cannot be used.\n\nDrop a ball from a certain height and the ball does not bounce back to the original height...that is because some of the energy was converted to sound (you hear the ball hitting the floor)...some was converted to heat (the ball and the spot on the floor where it hit are just a teeny bit warmer)\n\nFor the most part you can observe this "lost" energy (usually they are in the form of heat, light or sound)

it produces a lot of energy

The total amount of energy in a closed system remains constant.\nThis, however, was found to be untrue. It was later substituted for the conservation of Mass-Energy.\nThis was also disproven. In fact, if a tiny bit of energy is "borrowed" from nothing for a really short amount of time, it can create mass according to the equation:\nE*t = h/(2*pi) = 1.06*10^-34 Js\nOf course, for our pruposes, the conservation of energy works.

a-decreases\n\nand only about 10% of the energy is actually passed on

Its really strange you should say that. This has happened to two mates of mine recently. Maybe there is something in it..........

Energy that enters the system from the surroundings.

His role is discoving the equation of energy. E=MC squared.

Ok you need a bowl of water and the sun. The energy is trapped (at least temporarily) in the water, as heat.

A pendulum demonstrates the transfer of potential energy to kenitic energy.\n\nA light bulb demonstrates the transfer of electrical energy to light and heat.

Actually there are lots of instances of energy being converted into mass. The simplest case is pair production, when you have a high energy gramma ray pass close to an atome there is a chance that the photon will interacte at create an electron poistron pair. In doing so the photon losses energy equal two the combined mass of the two paricles,1.022 MeV.

Heisenberg notwithstanding, I have never observed my chair turn into energy, even as a transient state, no, not even for an instant.  It must be when I'm not looking.\n\nEnergy, if unused as work, turns into mass... in my case, a mass of fat around the middle.

Thermal energy IS heat.

The potential energy stays the same.

Many forms of energy exist around us. Energy cannot be created or destroyed, only changed from one form to another. If a person ever says that energy is lost, what really happens is that energy is spent or changed into different forms. It never really is lost. For example, if you use water energy to create mechanical energy, you might "lose" some energy by creating heat energy in the form of friction.

lol tahts simple and im 12! its not energy to mass its mass to energy! and atoms dont swell they simple crush together forming heat. as they hit light speed they disinegrate... or as thosse scienticsts say...
