rubber bands are not great at following hooks law because they suffer deformation more. That is, stretching a rubber band changes the rubber bands resting length more than with a spring within it's tolerances.
Dear Pyrrho would you be kind enough to review the very end of my latest video and leave a reply on Gary's response if you think he is wrong, I think he listens to you and this issue could be a way of getting him to learn a little humility! Basically am I correct to claim a same mass rolled of a 45 degree ramp at 2v lands 4x the distance as at 1v REGARDLESS OF HOW FAR THEY FALL. Thanks. .
