We now turn our attention away from simply describing how things move as we begin to consider WHY things move the way they do. The “why” of motion is called dynamics, and it’s where the fun really begins. Isaac Newton was a pioneer in the scientific examination of why things move, and his laws of motion form the foundation for our understanding of the topic. He also had tremendous flowy hair and was a solitary individual, considered by some to be simply reclusive and by others to be so egotistical as to be downright cruel. In your abundant free time, it’s worth it to look up his life story.
