Without the child the merry-go-round has a moment of inertia I which will change to I0 I mr2 when the child hops onto the edge. Moment Of Inertia Learn Physics Physics And Mathematics Physics Lessons MOI of ring circular plate spherical shell solid sphere and other objects. . We work with teachers at all levels to find the Cool Stuff - unique demonstration and laboratory tools and then provide lesson plans supportive teaching guides. However the moment of inertia should be conserved. Science Physics library Torque and angular momentum Torque moments and angular momentum Rotational inertia Learn how the distribution of mass can affect the difficulty of causing angular acceleration. Note that although the strict mathematical description requires a triple integral for many simple shapes the actual number of integrals. Learn about in
