Does energy barely leave the sphere?

[alex_boothby]

hi,

I've 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 I've 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 I am not sure from where u got that percentage

 

[alex_boothby]

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.
