Over the past week we continued our studies of rotational motion, adding momentum and torque to our bank of knowledge. Unfortunately for me, i missed the first two days of the unit last week while I was out of town. As a result I have spent most of the week confused and out of the loop on practice problems. This weekend, I finally decided to help myself and learn the material. I did this by watching parts of two lectures done by MIT professor Walter Lewin. I watched both videos and took notes on the material and although lewin is no Mr. Fullerton, I was still able to gain a much better understanding of the material.
