no you didnt, you started rambling on about potential energy and stuff.

scuse me OAM? didn't quite get that post.

[wigan_twins]

i would if i new what that was!!!!!!!!

[mike binder]

anyway did you get your dvd ,what is it maybe some 1 else as a copy and will help you both out ,isnt that why we are all on here freinds will be freinds

??? what about your age then

clever. if you are refering to gravity......


then it's E=MC2 (the 2 is squared)
that's equation for gravity......
but in a nutshell its a load of crap.

E=MC2= 0.111 x 300,000,000 x 300,000,000
= 10,000,000,000,000,000 Joules
This is an incredible amount of energy! A Joule is not a large unit of energy ... one Joule is about the energy released when you drop a textbook to the floor. But the amount of energy in 30 grams of hydrogen atoms is equivalent to burning hundreds of thousands of gallons of gasoline!


If you consider all the energy in the full kilogram of water, which also contains oxygen atoms, the total energy equivalent is close to 10 million gallons of gasoline!
Can all this energy really be released? Has it ever been?

The only way for ALL this energy to be released is for the kilogram of water to be totally annhilated. This process involves the complete destruction of matter, and occurs only when that matter meets an equal amount of antimatter ... a substance composed of mass with a negative charge. Antimatter does exist; it is observable as single subatomic particles in radioactive decay, and has been created in the laboratory. But it is rather short-lived (!), since it annihilates itself and an equal quantity of ordinary matter as soon as it encounters anything. For this reason, it has not yet been made in measurable quantities, so our kilogram of water can't be turned into energy by mixing it with 'antiwater'. At least, not yet.

Another phenomenon peculiar to small elementary particles like protons is that they combine. A single proton forms the nucleus of a hydrogen atom. Two protons are found in the nucleus of a helium atom. This is how the elements are formed ... all the way up to the heaviest naturally occuring substance, uranium, which has 92 protons in its nucleus.
It is possible to make two free protons (Hydrogen nuclei) come together to make the beginnings of a helium nucleus. This requires that the protons be hurled at each other at a very high speed. This process occurs in the sun, but can also be replicated on earth with lasers, magnets, or in the center of an atomic bomb. The process is called nuclear fusion.
What makes it interesting is that when the two protons are forced to combine, they don't need as much of their energy (or mass). Two protons stuck together have less mass than two single separate protons!
When the protons are forced together, this extra mass is released ... as energy! Typically this amounts to about 7% of the total mass, converted to an amount of energy predictable using the formula .

Elements heavier than iron are unstable. Some of them are very unstable! This means that their nuclei, composed of many positively charged protons, which want to repel from each other, are liable to fall apart at any moment! We call atoms like this radioactive.
Uranium, for example, is radioactive. Every second, many of the atoms in a chunk of uranium are falling apart. When this happens, the pieces, which are now new elements (with fewer protons) are LESS massive in total than the original uranium atoms. The extra mass disappears as energy ... again according to the formula ! This process is called nuclear fission.

Both these nuclear reactions release a small portion of the mass involved as energy. Large amounts of energy! You are probably more familiar with their uses. Nuclear fusion is what powers a modern nuclear warhead. Nuclear fission (less powerful) is what happens in an atomic bomb (like the ones used against Japan in WWII), or in a nuclear power plant.

Albert Einstein was able to see where an understanding of this formula would lead. Although peaceful by nature and politics, he helped write a letter to the President of the United States, urging him to fund research into the development of an atomic bomb ... before the Nazis or Japan developed their own first. The result was the Manhatten Project, which did in fact produce the first tangible evidence of ... the atomic bomb![/quote]

How's this thread gone from where's my dvd to the theory of nuclear fission? What a link

were great wiganers arent we bet a sts site couldnt get round to this

i began to read that, quite a bit, and then realised i needed a life. you should be telling yourself the same thing

We used the Newtonian equations, which are valid in "normal" conditions, but don't apply at high (approaching the speed of light) speeds or in high gravity fields.
