The Influence of Magnus Effect on The Flying Distance of Baseball and Golf

Abstract

The Magnus effect is also very common in ball sports, so the study of the causes and applications of the Magnus effect in ball sports is of great significance and practical importance to the teaching level, training effect, and competition performance of ball sports. The effect of the Magnus effect on baseball and golf will therefore be discussed. In the case of baseball, we will consider the effects of drag and the Magnus effect on its motion and establish a three-plane system consisting of gravity, drag, and the Magnus force, thus demonstrating the interaction of the three forces in the trajectory of the baseball. The concept of projectile motion is introduced in mathematics, physics, and engineering disciplines in a vacuum environment, and when applied to real-life situations, the theory differs significantly from the ideal state. This is why baseball's trajectory in a non-ideal situation is studied. In the case of golf balls, the results are subject to large errors because only the air resistance is taken into account in the discussion of the golf ball range problem, and the effect of the Magnus force on its range is ignored. According to fluid dynamics, a golf ball moving through the air is subjected to bypassing (air) resistance and Magnus force. The article will therefore also look at the effect of the bending (air) resistance and the Magnus force on its movement.
