I have a qualitative understanding of quantum chromodynamics within nucleons and between nucleons, but I do not understand the math behind some of the physics like quark confinement. What is the math function that dictates the force experienced in quark confinement? What is a simple analogy for ...

Consider a 10 kg box on the bed of a truck accelerating at 1 m/s^2. Consider a reference frame where it starts at 0 m/s and ends at 10 m/s and then consider a reference frame where it starts at -5 m/s and ends at 5 m/s. The work is positive in the first reference frame and zero in the second. I...

If we look at a particle moving in the positive $x$ direction from a frame that is accelerating in the positive $y$ direction then its acceleration will be different from that in an inertial frame and hence the force on the particle must also be different in this frame. Is this right?

I am struggling to reconcile definition of voltage as work done moving unit of electric charge between two points in electric field and voltage in Ohm's law. In work definition, everything is more or less clear, but in Ohm's law we are measuring voltage at a point so work done should be very smal...
