Einstein gave us E=mc2, and this equation is what is called the mass-energy equivalence. What the equation says is that there is a direct relationship between matter (something with mass, m) and energy (e). If a specific amount of mass is converted into energy, there will be a specific amount of energy created. If a specific amount of energy is converted into mass, there will be a specific amount of mass created. But how much? Let's look.If a specific amount of mass creates a specific amount of energy when converted and we double the amount of mass, we'll get double the amount of energy when it's converted. If a specific amount of energy is converted into mass and we double the amount of energy, we'll get double the amount of mass when we convert it. One more thing.The conversion factor when changing mass to energy or energy to mass is the square of the speed of light (c2). If one kilogram of mass is converted into energy, the equation will look like this:E = mc2 = 1 x (3 x 108)2 = 9 x 1016 Joules of energy.That's a lot of energy. Over 4 million average homes could run for a year on that energy. There is a huge amount of energy in matter if we convert it all to energy. Use the link to learn more.

The Watt hour efficiency is the ratio of the amount of energy available during the discharge of an accumulator to the amount of energy put in during charge.

Time is not dependent upon anything. Time is what it is. However, the amount of time necessary for something to happen IS dependent upon the amount of energy put into it, the amount of mass it is happening to and the distance across which it is happening.

at the top of the ramp the toy has a certain amount of potential energy. The amount of this energy depends on the height of the ramp and the weight of the toy. (The toy's weight is dependent on its mass and the force of gravity.) As the toy rolls down the ramp this potential energy is converted to two other types of energy: Kinetic energy and heat energy. The amount of heat energy depends on friction and air resistance. The lower the total resistance the more kinetic energy, and the more speed, the toy has at the bottom of the ramp.

You are thinking of the conservation of energy law which states energy can neither ber created or destroyed.

It isn't entirely clear whether total energy is conserved in General Relativity, or whether the total energy is even clearly defined in all cases. But in general it is assumed that the total amount of energy doesn't change over time.

The total amount of energy in the universe eye is zero.

Visible light has a higher frequency, a higher energy per photon, and a smaller wavelength, compared to infrared.

The total energy and the mass equivalent energy in the universe remain constant. That "total" energy never changes.

Actually interesting enough it may be as simple as just ZERO. Because by you asking the amount of energy in the Universe, you are forgetting about the negative amount of energy that is also made up in our universe. For every positive energy there should be a negative, with simple math skills this basically adds up to zero.

We do not think it does change.

light is a form of energy and energy cannot be destroyed or created only changed so the amount of possible light is equal to the amount of energy in the universe
