# Moment of inertia of an object with uneven distribution of weight

sungj25
I'm doing an experiment and I have to calculate calculate rotational kinetic energy of this can rolling down an inclined plane.
According to the equation, Er=1/2Iw^2, I=mr^2, and w=v/r (no slipping effect) right?
but doesn't I=mr^2 apply only when the weight is evenly distributed throughout the axis?

In my experiment, I'm going to add mass only on one side of an empty cylindrical can (using bluetag). Will I be still able to calculate the inertia using this I=mr^2 equation?

$I=\int r^{2} dm$
