Rotational Kinetic Energy Video Lecture | Physics for EmSAT Achieve

1. What is rotational kinetic energy?$#
Ans. Rotational kinetic energy is the energy an object possesses due to its rotational motion. It depends on the object's moment of inertia and angular velocity.

2. How is rotational kinetic energy calculated?$#
Ans. The formula to calculate rotational kinetic energy is KE = 0.5 * I * ω^2, where KE is the rotational kinetic energy, I is the moment of inertia, and ω is the angular velocity.

3. What are the units of rotational kinetic energy?$#
Ans. The units of rotational kinetic energy are Joules (J), which is the same as the unit for linear kinetic energy.

4. How does rotational kinetic energy differ from linear kinetic energy?$#
Ans. Rotational kinetic energy is associated with the spinning motion of an object, while linear kinetic energy is related to the object's linear motion in a straight line.

5. Can an object have both rotational and linear kinetic energy simultaneously?$#
Ans. Yes, an object can have both rotational and linear kinetic energy at the same time if it is moving in a straight line and rotating simultaneously.
