4 ) Identify and analyze forces responsible for changes in rotational motion and develop an understanding of the effect of rotational inertia on the motion of a rotating object (e.g., merry-go-round, spinning toy, spinning figure skater, stellar collapse [supernova], rapidly spinning pulsar).

Did you know that at a certain point on a moving wheel there's no motion? It's all relative, right? Prepare to have your mind blown in this episode of Crash Course Physics where Dr. Shini delves into the world of rotational motion!

In this episode of Crash Course Physics, Dr. Shini discusses what torque is, how it works, why it works, and what it all has to do with this thing called "Moment of Inertia."

In this video, Dr. Shini discusses centripetal force, centrifugal force, and a few other bits of physics to help us understand uniform circular motion.

In this episode of Crash Course Physics, Dr. Shini talks about the realities of the apple story and how Newtonian Gravity is more than a little important.
