# center of gravity is not calculated using vertical ball mill

Parallel Axis Theorem/Center of Mass Physics ForumsThe system center of mass is now the axis of rotation to utilize the parallel axis theorem so find the moments of inertia for the rod alone and the ball alone about the center of mass axis integation is required for the rod but not for the ball because it can be treated as a point mass at the center of gravity**-center of gravity is not calculated using vertical ball mill-**,How to calculate the acceleration of a ball thrown upwards To measure the acceleration of an object measure its change in velocity with time On earth the change in velocity will be 32 feet/second/second in a downwards direction Downwards means towards the center of gravity which in the case of the earth and a typical ball would be approximately the ……
