Does energy barely leave the sphere?

  1. Mar 14, 2006 #1

    ive just found ou that ke (translation) + ke (rotational) = Potetntial

    i.e • ½ I *angular speed(squared) + 1/2mv(squared) = mgh

    is ther anything else i can derive from this. as that is all basically ive written, and that , This proves that hardly any energy is lost, with an average of less than 0.000001738% loss of energy, it shows that the energy does not leave the sphere

    you have to be more specific... like perhaps tell us the question... because im not sure from where u got that percentage

    its a ball bearing rolling down a slope, and then released at different distances

    Why should energy be lost from sphere? The equation shows energy in the sphere is conserved. As stunner was stunned, even I am stunned with the percentage of energy loss you gave. An ideal ball bearing, which is an ideal sphere will never lose an energy.
