Miscellaneous - Backspin
In order to impart noticeable backspin
on a golf ball it is imperative to hit the ball prior
to taking a divot. This means the club is descending
and contacting the ball as it is traveling toward the
ground. When done properly you should notice your divot
will begin somewhere ahead of where the back side of
the ball was prior to the shot. The further ahead of
this point the divot begins indicates the amount of
spin placed upon the ball.
The short form technical description of
why this causes backspin on the ball goes something
like this: The groves of the face of the club grab the
ball on the way down pulling the back of the ball towards
the ground while the face of the club impacts the back
of the ball providing it the required forward momentum.
As such the ball is flying through the air with the
backspin that will assist in offsetting the forward
momentum once the ball hits the ground (hopefully the
green) causing it to check up and impress all your friends.
When in the rough, applying backspin
to the ball becomes much more difficult because of the
extra give of the longer grass beneath the ball. As
the club descends on the ball and the groves grab the
surface the ball it moves with the downward blow into
the rough a fraction of a second prior to beginning
its flight towards the intended target thus reducing
the spin placed on the ball.
Although it is fairly obvious from the
discussion above, it is prudent to mention that the
grooves on the face of your clubs should be clear of
debris (i.e. dirt, sand, mud, etc.) in order for the
grooves to have any edge on them which is really what
grabs the ball at impact.
