The problem I’m then confronted with is this: the coffee gets cold. But I only like coffee that is at least lukewarm. So how does my coffee stay warm? Let’s do some science…

Using physics to throw, kick, and hit balls further

A common goal in many sports is to throw, kick, or hit a ball as far as possible. To reach this goal is simple: you apply all the force you have to the ball. But that’s not all. You also have to choose the best launch angle. The angle plays an important role in determining the distance that flying objects travel.

Physics of a curveball

When the Texas Rangers were in the World Series again, I thought about the physics of pitching curveballs. If you know the science behind it, you probably don’t pitch better curveballs, but it’s interesting to know why the ball moves the way it does. But who knows, maybe it does. Let me know if it actually helps to improve your pitching. Continue reading “Physics of a curveball”
