comment Kepler's Laws to Determine Radius of Circular Orbit
Try plotting $r^{-2}-r^{-1}-0.01\cdot r^{-3}$ instead. The correction is small. $c^{-2}$ is small.

comment Similar effect to gravity horizontally?
Your calculations are wrong (you set force=energy, which is like saying "my clock reads five meters" - it doesn't make sense!) And your units are incorrect (your speed is a measure of acceleration). Are you expectong someone to fly towards the back of a moving truck when they jump? This is incorrect! If you jump on an airplane you notice nothing special different than jumping on the ground.

comment Insight into Torricelli's Equation ($v^2=u^2+2as$)
@pdmclean so that's the meaning of Torricelli's equation! It is an expression of conservation of energy and what it shares in common with Torricelli's law is that they were both formulated by the same person.

comment Water Waves in the Wake of a Boat
I don't think this is the case. Ex. i.stack.imgur.com/PaSas.jpg seems to have no asymmetry and the lines of constant phase (or maximums if you prefer) still bend outwards!
