"The coefficient of friction IS A FUNCTION OF THE SURFACES."

of course since the friction coeficient is the tangent of the angle of the ramp when the box starts to move

so then you admitt those links saying friction being INDEPENDENT OF SURFACE are wrong

also you admit einstein couldnt have measured atmospheric starlight bending

then how COULD that eclipse have proof him and give him the nobel prize, maybe a fraud?

edit:

thsi thread is very RELEVANT in gravity falsified

edit:

outlaw youre the perfect exmplae of sophist with slight trolling for your slight personal attacaks

seems you want to convince somebody else not me for your ridiculous arguments

will you plz answer me this clear question with yes or no plz?
