Additional potential energy of the ball when raise a height h is: m.g.h

In this case m=2, g=9.8 and h=10m, so Delta(PE) = 196 Joules

How is the moment of inertia of a body about an axis defined? Does italso, If the velocity of a rolling ball doubles, does the moment of inertia change?

thankyou.

include anything except the radial mass distribution?
