WebA turntable has a moment of inertia of 3.0 × 10−2 kg⋅m2 and spins freely on a frictionless bearing at 25 rev/min. A 0.30-kg ball of putty is dropped vertically on the turntable and sticks at a point 0.10 m from the center. By what factor does the kinetic energy of the system change after the putty is dropped onto the turntable? 0.91 WebThe moment of inertia is an object’s tendency to resist angular acceleration (rotational acceleration). It controls its spinning rate. An object with more mass at the center has a lower moment of inertia, and the lower its moment of inertia, the faster its rotation.
