Things really get spinning with a discussion of accelerated circular motion. Then the Standard Deviants cover rotational motion, which is the rotation of objects like planets. Along the way you'll learn about radical radians and other science lingo. Finally, we'll look at linear momentum and its companion, the Principle of Conservation of Linear Momentum.
