# [Rant] And again: our mass comes from the kinetic and potential energy inside nucleons

Yesterday you could read on this blog that mass and energy are the same, as mass is energy compressed in a given space in a given form. Nucleons, the subatomic particles that form the nucleus, ie the protons and neutrons, contain most of our mass and inside them there are quarks which are bound by the strong force into a “subatomic threesome”.

That strong force is, in fact, the kinetic energy and potential energy from within the nucleons, but the quarks amount only to a max of 2% of the atom’s total mass. Most of the mass is, therefore, coming from the energy that binds the quarks together. Smashing, ain’t it? Knowing that you’re pure freaking energy and that mass, as we knew it, doesn’t even exist. Cool, eh?

Now, let’s learn more about mass, inertial mass and why a hollow tube goes down a slope slower than a full, solid tube. Why? Because you need more energy to put that hollow tube into motion as all the mass is in the tube walls, not spread across the entire solid.

That would mean, in a sense that we all could better understand, that bicycle wheels should be made of solid materials, not the common wheel with all the weight distributed along the outside of the circle.

Check this out:

Also, given a inertial reference frame and a gravitational reference frame, mass and weight are interchangeable terms. Mass and weight are almost the same:

And, of course, you should not forget that weight is given by the gravitational force, which is NOT a force. In fact, gravity is a space-time distortion:

And of course, who the heck cares that we’re only 2% actual mass and 98% energy and that we, maybe, will be able to invent some anti-gravity ships sometimes in the future if we learn to harness anti-matter like real cowboys? No, really, who cares?
