When you swing a knife or a sword, you may not be thinking about physics—but physics is definitely at play. The difference in how fast they move, how much force they deliver, and how they feel in your hand all comes down to principles like angular momentum and angular velocity. Interestingly, these same concepts help explain the evolution of the modern tennis forehand, particularly in how players wield lightweight, stiff racquets to produce explosive power. Let’s dive into the science of rotational motion and then explore how…
