Hello. Sorry for being annoying, I've posted like three questions today. But I'm studying nuclear chemistry and still somewhat confused regarding the binding energy and mass defect and their relation with the strong nuclear force.. 1) in this Hank Green video... He says that the mass defect is actually present in the form of energy that ties the nucleones together. Isn't that what the strong nuclear force does? Does this mean they're both the same thing? What's the relation between the two? 2) in E=MC^2.. I can see why the mass defect matters to calculate the binding energy. but how does the speed of light constant matter in this case? 3) Seeing that the binding energy is the energy needed to split the nucleones. and the strong nuclear force is what ties them together. Would it be correct to say they're opposites? and could they be calculated using that assumption? thanks in advance..
