Physics Unit 11 - Rotational Energy and Angular Momentum

High School, College, and AP Physics 1

This is the final course in our major unit covering rotational motion in which we cover rotational energy and momentum. We will be applying all of our underlying knowledge of mechanical energy and momentum here to rotating objects and systems. In this course you will see what factors effect how mechanical energy can transfer to and from rotational kinetic energy and how it is conserved in systems. One fun way in which we can do this is by taking various objects and racing them down controlled inclines to see how their attributes such as diameter, mass, and distribution come in to play. What would win a race down a hill? A bowling ball, tennis ball, or can of chicken soup? Believe it or not the answer is not as easy as you may think!

We will also cover in great depth how momentum of rotating bodies and systems can be analyzed and how we can connect our prior knowledge on linear momentum to rotation. What effects a system's rotational speed? How can a figure skater seemingly change rotational speeds just be moving their arms in and out? We will also explore what happens when a net torque is applied to a rotating system.

There is a lot involved in this course! Make sure you take good notes and work through all of the examples and worksheets!
