Why do you need spin on a golf ball in golf?

Answer 1

All clubs put backspin on the ball (unless you totally duff it). As the ball moves though the air with backspin lift is created. This is called the Magnus effect, it is similar to Bernoulli affect. The spinning creates a pressure differential and thus lift.

As to whether or not a ball releases, checks, or spins back upon landing is dependent upon several variables: Spin rate upon landing, angle of decent, angle of the surface, ball velocity, hardness of the ground, and the coefficient of friction between the ball and the landing surface.

ANSWER:

Back spin on a Golf ball causes the golf ball to spin backwards as it travels away from the person who hit the ball. Hitting a golf ball with a back spin will allow the golf ball to travel a great distance with a high arc. Setting a golf ball in motion with a back spin also will help to bring the ball to a stop when it hits the ground.
