Elevation Changes & Golf Club Selection
It's
obvious to all experienced golfers that when hitting uphill, you
need to hit more club and when hitting downhill, you need to hit
less club. The question is how much more or less. Of course, it
depends on many conditions. This page will discuss and deal with
the effect of elevation changes alone (without wind, rain, cold,
etc) so that you can improve your club selection and lower your
score.
Try out my Distance
Calculator. You can input different conditions to
see how they affect your tee shots.
The
trajectory of a golf ball is now well understood. It depends on
ball velocity, trajectory, and spin as well as on air temperature,
humidity and density. Below is a graphic of the trajectory of a
golf ball hit with a driver, 5-iron, and
9-iron.

Note that
in the first part of each trajectory, the path of the ball steepens.
This is due to the lift created by the spin of the ball. Note as
well, that the trajectory of each is different at impact. The 9-iron's
impact is the steepest and the Driver's impact is the least steep.
Because of this, a Driver's range is more greatly affected by elevation
changes than a 5-iron and the 5-iron's is more greatly affected
than the 9-iron's. For every yard of fall, the Driver ball travels
farther. If on a tee shot, for instance, the ball were to land 20
yards below the tee in elevation, it would travel horizontally 15
yards farther.
I've used
my golf ball trajectory computer model to calculate the actual
distances uphill and downhill shots play for all the various
clubs. You can instantly download
my report along with similar
reports that explain how much wind affects your shots and how
much slope affects your putts. Get them here.
Or, you can just order the report on elevation
changes here for only $5.99.
