Velocity
Acceleration
Mass
Force
3. The formula for rotational kinetic energy is KE_rot = .
4. Angular velocity is measured in units of .
5. A larger moment of inertia means an object is to change its rotational state of motion.
6. A solid cylinder and a hollow cylinder of the same mass and radius are released from rest at the top of an incline. Which one will reach the bottom first and why? Assume they roll without slipping.
