Question
A solid cylinder and a hoop have the same mass and radius. If both are rotating with the same speed, which will have the largest rotational kinetic energy?
Step 1
Step 1: The rotational kinetic energy (KE) for any rotating object is given by the formula: \[ KE = \frac{1}{2} I \omega^2 \] where \(I\) is the moment of inertia and \(\omega\) is the angular velocity. Show more…

A solid cylinder and a hollow cylinder of the same mass and radius are rolling along level ground at the same speed. Which has more kinetic energy?
A solid sphere of radius R, a solid cylinder of radius R, and a hollow cylinder of radius R all have the same mass, and all three are rotating with the same angular velocity. The sphere is rotating around an axis through its center, and each cylinder is rotating around its symmetry axis. Which one has the greatest rotational kinetic energy? The solid cylinder. All three objects have the same rotational kinetic energy. The hollow cylinder. The solid sphere. Both cylinders have the same rotational kinetic energy.
