- we must be 2 out of 500 peopel (max) who play it damn
getting a game pre-ordered
I play it all the time. But not the multiplayer because it sucks and shouldnt be in the game.

- Weight is a force, there is the same mass for people questioning
actually, the mass of a spring (and therefore its weight as well) actually does change as a result of compression. Compressing a spring requires an input of energy to a system (the spring). Einstein's equation e=mc^2 says that mass and energy are the same thing. Energy IS mass. Therefore the spring's actual mass will increase (if only by a tiny bit) when you compress it. Check out http://debunkeymonkey.blogspot.ca/2009/08/does-compressed-spring-weigh-more-than .html
weight is a specifc type of force, downward force towards the center of earth. The closer something is, the stronger the gravitational pull. By compressing the spring there is less distance from the center of the earth to the entire spring increasing the force.
since the mass remains constant and assuming that fucking gravity doesnt change just because a spring is compressed (which is stupid just thinking about it) that fucking springs weight should remain constant.
except the mass doesn't stay constant. See my comment (110). oh, and fuck fucking fuck, I guess
Which one are you commenting on?
i would imagine he's commenting on the compressed spring one
If so, then he's right about weight being a force, but apparently the mass of the spring does change as energy is added to the spring.
it's explained by e=mc², adding energy to something also increases mass because m=e/c²
that is false. The increase in energy would come from transfer of energy from what ever object was applying the force to the spring to compress it. That means that the spring would not gain mass. The only way ti would gain mass is if you physically added onto the spring itself.
Elastic Energy, the type of energy that would be gained by the compression of the spring as well as the stretching of the spring, is E=.5*k*(delta x^2) where k equals the spring constant and delta x equals the change in distance in compression or stretching.
Taking this into account, when measuring the whole energy of spring we do as follows:
this is energy original
>Eo = m*c^2
assuming that the spring is sitting still and we are not factoring in temperature or any other factors, the original energy of a spring that is not compressed or stretched would be equal to the mass times c^2.
this is final energy after compression
>Ef = (m*c^2) + [.5*k*(delta x^2) ]
Now you add the energy of the spring before to the added energy from what ever source compressed or stretched the spring.
Playing the energy game is complicated and can confuse many people. It is hard to understand and that is understandable. But, with the above information, it is clear that a spring would not become more massive due to compression.
