The Many Balls of Physics: Whatever the Sport, Keep Your Eye on the Ball
Physics applies to any sport, which uses a ball in any part of the game.
The physics of golfswing controls how far and straight the ball will go as well as how much loft is applied.
In baseball, the physics of a curveball can make the target very difficult for even experienced batters to hit well. The physics of bowling controls the path of the ball.
Sir Isaac Newton's Third Law of Motion states that for every action, there will be an equal and opposite reaction. This simple statement controls the physicals of golf swing, ball throwing, tossing, kicking, hitting or roll.
Why does a ball curve? For it to curve, it has to be spinning. The spin causes the airspeed on different areas of the ball to cause differences in the path of the ball. As a ball curves, the direction of the force due to the differential pressure changes, allowing the ball to curve even more. What direction the ball curves depends on the axis of the spin; this effect, known as the Magnus Effect, can cause the ball to veer sideways, drop down suddenly or even go upward.
Those who understand the physics of golfswing know the trick is to keep your eye on the ball at all times and expect the unexpected. Expert golfers, bowlers and baseball players can make the ball go in the most unexpected paths possible. To improve your game, no matter what your game may be, keep your eye on the ball.
