Answer #1

1.The potential energy arises from a variety of interaction including elastic,graviataional etc the potential energy changes continuously the comparison with the atom will only be concerned with the shape of the potential energy curve not with the origin of interactions so it is difficult to plot a straight line .again we have not measured the kinetic energy so we can not put the value only one of the reference axis. So potentual and kinetic graphs are always curved.

A glider is free to move along an air track, which is raised at an angle of 45° above a horizontal tabletop. The glider is first placed at the top of the track so that it is at a height h above the tabletop, and after being released, it reaches a speed v at the bottom of the track. Assuming friction acts on the glider during its motion, which of the following statements is(are) true when the glider has reached...

If the formula for kinetic energy is KE=1/2mv^2 then why is Einstein’s equation for the total energy in a given mass E=mc^2? Shouldn’t it be E=1/2mc^2? They are kind of the same equation and in my mind Einstein was basically declaring that the energy a given mass would be limited by the maximum velocity observed in the universe.
