Read each question carefully and provide your best answer. Show all your work for calculation problems.
1. Which of the following best describes rotational kinetic energy?
Energy due to linear motion.
Energy stored in a rotating object.
Potential energy of an object at height.
Energy transferred by heat.
2. The moment of inertia of an object depends on its:
Linear velocity.
Mass distribution and shape.
Temperature.
Volume.
3. The formula for rotational kinetic energy is KE_rot = , where I is the moment of inertia and ω is the angular velocity.
4. A larger moment of inertia means an object is to change its rotational state.
5. Explain the analogy between linear kinetic energy and rotational kinetic energy, identifying corresponding terms.
6. A solid cylinder with a mass of 5 kg and a radius of 0.2 m rotates at an angular velocity of 10 rad/s. Calculate its rotational kinetic energy. (Moment of inertia for a solid cylinder I = (1/2)MR²)
7. Doubling the angular velocity of a rotating object will double its rotational kinetic energy.
