I understand! Thanks a lot for the quick replies everyone! I love this site.

Oh ok, SO the equations in my textbook that aren't E=mc2 are just separate eqns for the subtopics of relativistic momentum and energy, and they have nothing to do with E=mc2... ?? I havean eqn that combines dilated mass and momentum and an eqn that combimes E=mc2 dilated mass, and kinetic...

Could someone just reply and say if these points makes sense for relativistic mass, -The other measure of mass (relativistic mass) is dependent on the velocity of the observer. -This relativistic mass is a product of the increase in momentum relative to an external frame of reference

Yes, that's the equation I am referring to, just slightly simplified. I think I'm understanding this now,one more question tho? The relativistic version of the mass-energy equivalence is compared with momentum because the faster a mass goes, the more momentum it has, which causes its...

I think Einstein just generalized it, basically he was saying no matter what, the amount of energy in an object is always going to equal the mass times the speed of light and vice versa. So basically "if that object became complete energy it would have this much energy or something like that."...

Homework Statement Einstein's E=mc2 Homework Equations E=mc2, mass dilation, relativistic energy. The Attempt at a Solution Does Einstein's E=mc2 involve mass and energy as relative values? or does the equation mc2=moc2+Ek ie: the same eqn just with mass dilation and...

I understand this but I don't understand how momentum can be relative... What is dilated mass?How can energy be relative aswell?

Homework Statement My textbook is only confusing me further and I need to understand this for a presentation in front of the class! The chapter is entitled Mass-Energy Equivalence, with sub titles Relativistic Momentum and Relativistic Energy. I don't understand relativity, I'm reading the...

Its okay, i figured it out. I'm an idiot...

Is it okay to get this thread started up again I have the same question and similar difficulties... Even if I do as you said, and use E=E1+E2, I still have the problem of having either the two variables of r, or no variable I'm so confused. If I solve for values of E at a specific point...
