Energy and mass are interchangable ?How can this be?

Question

Since energy depends how fast a mass move, it' s process.?The how can energy become mass? If I have one pound of gold & I give it power so it moves at the speed of light =Im going to get an infinte number of kg of gold out of it?

Answer 1

That's right through Einstiens equation of relativity if a piece of gold is moving the speed of light then it will be infinitly massive. but how would you spend all that gold if it were moving so fast :).

Answer 2

the motion of matter has nothing to do with its inherent energy. The energy referred to by the equation E=mc^2 is referring to the energy of the forces inside the atom, not the force matter can impart on other matter due to motion. Even if you could move a mass of gold up to the speed of light, and it would gain mass getting close to the speed of light, when you slowed it back down, it would be the same amount you started with.

Answer 3

lets say you accelerate the gold to near the speed of light ( because matter has a speed limit ). the gold only increases in size to an outside observer !

in other words, if you WERE the gold ( conscious gold :) ) , your own size would still be perceived or measured as 1 pound. ( this is a fact of relativity ).

the mass and speed of all material objects are RELATIVE to each other and NOT absolute. the inherent energy of matter is however absolutely measurable ( E=MC^2 ) . this is because its inherent energy is NOT related to its speed BUT simply its mass ONLY.

this why matter appears to increase its mass as its velocity increases ( to reflect its total energy content ! ).

hope i answered your question from a different angle !

:)

Answer 4

Since we are not experiencing the change in mass of a moving object at ordinary speeds we assume that the mass is a constant.

Experiments with fast moving particles has proved that the mass increases with speed.

Hence we have to accept it.

Answer 5

its related by the equation e = mc if talking bout nuclear fusion and fission this is the excess mass or binding energy, which is the difference between the mass of the nucleus and its individual nucleons when split up. To completely convert mass into energy, anti -matter can also be used which can change any mass into pure energy..

Answer 6

Simply stated: Mass and Energy are different aspects of the same thing. They are are interchangeable. The best way for to comprehend it, is to look at Mass to Energy conversion ratios. You may contact me directly and I will be glad to explain in detail. (OR) Pick my answer as the best one...and I will put the ratios in the comment section for all others to see and learn from as well as you.

Answer 7

Interchangable? hmm...

Mass IS energy. It is simply energy in a different form. As an analogy that is easy to understand, I will mention water; it can be a solid, liquid and gas, just like energy can manifest itself in many different ways.

The entire universe is energy really when you get down to it >.>

Answer 8

It can be in the same way that time and space are interchangable.

Go take a couple of years of University level Physics courses (and the prerequisite math classes) and you'll get all of your questions answered.
