Activity: Moment of Inertia

IB Physics: Activity: Moment of Inertia

In the last activity we applied Newton"s law to a small mass on a light rod, now we will add a second mass.Each mass is rotating about the pivot (left end), this means that there is a Torque acting on each of themThe total torque, T = T1 + T2.SoThe moment of inertia of a rigid body is defined as the sum of all the particles of mass multiplied by the square of their distance from the pivot.
