Does a baseball have more kinetic energy if it is spinning? In this lesson, we'll learn how to determine the rotational kinetic energy of an object so we can figure out how much more energy the baseball has.
Angular momentum is constant where there is no net torque, just like how linear momentum is constant when there is no net force. In this lesson, we'll learn about the conservation of angular momentum and how to apply the new conservation law to solve problems.
Everything you've learned about motion, forces, energy, and momentum can be reused to analyze rotating objects. There are some differences, though. Here, you'll learn about rotational motion, moments, torque, and angular momentum.
