In Chapter 6, we introduced the concept of momentum, and explored how it was conserved. Rotating objects also have angular momentum, which is independently conserved if a body is moving and rotating simultaneously. Our ball bearings and marbles were rolling when they collided in the last chapter, but we ignored the effects this caused to focus on the linear momentum. Here, we do a few experiments to characterize the rotational effects.
In the last chapter, we introduced the idea of torque and how rotation gets started. Now, we take a deep breath and dive into some of the calculus involved to compute the motions of rotating bodies. Measuring rotating systems accurately with low-cost equipment is tricky. However, we ...
