when i add ke translational + ke roatational, i don't get potential which i should, although i was wondering if maybe it was due to slipping although i thought it would still be closer than i got
does this sound right?
ke trans(0.002520831)+ke rotational (0.001008332) = 0.003529163
and
pe=0.014278472
as you can see not very near it!
is this right or have i gone wrong?
the exp was rolling a ball bearing down a 5 degree slope and these calcs were from the 1m release mark. the radius is 0.00765m
thanks
to get the angular speed i used linear V/R (radius)
i got linear v by divinding distance by time.
