Ball Flight Laws - The 5 Laws of Ball Flight Explained 2020

These laws are absolutes. They are the physical forces that combine when hitting a golf ball and dictate how it reacts in flight. Understanding these laws helps to explain the answers to the key questions of distance and direction. These laws shouldn't be confused with the golf swing itself, which are subject to principles.

Work (physics) - Wikipedia

This result can be understood more simply by considering the torque as arising from a force of constant magnitude F, being applied perpendicularly to a lever arm at a distance r, as shown in the figure.This force will act through the distance along the circular arc s = rφ, so the work done is = =. Introduce the torque τ = Fr, to obtain = =, as presented above.

The most common ball material within a ball bearing is stainless steel. Stainless steel balls are the most cost- effective choice, but they are heavier than both the plastic and glass options, and they are magnetic, which can be a detriment to some applications. Glass balls are ideal when a metal-free solution is needed.
