The
Putting Vectors
As
early as 1686, the great mathematician and physicist
Sir Isaac Newton had solved the golf swing problem
for us. Newton's second law of motion describes
the relationship among the putter or club head's
mass (equivalent to the weight of the putter or
club head), the momentum (mass times its swing
velocity or speed), the force the putter or club
head generates, and the direction of the force
to be applied to the ball. It can be expressed
by the following equation
F
= m * v / t |
where
F is the force, m is the mass
of the putter or club head, and v is
the velocity (speed) of the putting or club head at
impact, t is the downswing time from the top to the
impact. The velocity, force,
acceleration (change in velocity of
club swing speed), and momentum have
both a magnitude and a direction associated with them.
We
do not have to get into the detail of the theory of
physics. The important fact is that a swing force will
cause a change in speed; and likewise, a change in swing
speed will generate a force. The force
has a direction associated with the swing plane when
it applies to the ball. This physics law of motion has
great applications in golf for putting, chipping and
full swing. We can apply the physics law of motion to
putting strokes by putting vectors.
As
shown in Figures 1, a golf putting stroke can be described
by the movement of two putting vectors: the putter
face vector and the putter
shaft vector.
The putter face vector
is defined as the direction perpendicular to the putter
face through the sweet spot of the putter; the putter
shaft vector is defined as the direction
parallel to the putter's shaft. The putter
face vector and the putter
shaft vector are perpendicular to each
other on the putting plane by the nature of how the
putter is made. Note that every putter has a lie angle
of about 72 degrees and the putter
shaft vector is NOT perpendicular to
the the ground. |
According
to Newton's second law of motion, to hit the ball rolling
straight along a selected target line, the putting stroke
can not be straight back and straight through the target line.
The putter head is traveling along a putting arc (inside-to-inside
path in a 3 dimentional space) while keeping the putter face
staying square to the arc. The curve of the putting arc is
different for every golfer. It depends on the height of the
golfer and the setup.
To stroke the ball rolling straight along the selected target
line, your putting stroke has to meet the following requirements
as described by the putting vectors:
(1)
The putter face vector stays tangent to the
arc all the time on the putting plane, ie., the projection
of the putter face vector from the shaft direction has to
stay overlapping the target line (Figure 2);
(2)
The putter face has to be squate to the arc during the putting
stroke (Figure 3);
(3)
The putter shaft vector shall point to the
target line all the time (Figure4).

| Unforfornately,
all above are not visiavle to golfers since the putter
head to too small and does not have the resolution
for golfers to tell its face orientation within less
than 1.5 seconds while the putting stroke has to be
completed.The only way to identify the putting parameters
is to use complicated computer system, such as Science
& Motion Sport system (SAM PuttLab). The LaserT
(US Pat. Pend.) is a great invention to provide the
visulization for your putting stroke. The putting
vectors are implemented by a "T"
line laser beam projection system. The Putter Shaft
Vector is implemented by adjusting the "T"
projection direction parallel to the putter shaft,
the putter face is aligned by the horizontal "T"
arm and the Putter face vector is implented by the
vertical "T"
arm. The entire putting vector system is implemented
step by step as
(a)
attaching the LaserT
to the putter ( as shown in Figure 5);
(b) turn on the LaserT
projection;
(c) adjusting the T
projection to be parallel to the putter shaft;
(d) rotating the T
projection to align a first arm of the T to be parallel
to the putter face with the second arm of the T
being directed away from the putter face;
(e) centering a cross-point of the T
projection through the sweet spot of the putter head;
(f) aligning the second arm of the T
projection to be overlapped with the desired target
line; and
(g) maintaining the second arm of the T
projection overlapping the desired travel path during
your putting stroke.
The
putting vector system is simple and easy to use. It
will give a perfect putting stroke for any putter,
used by any golfer, right handed or lefted handed.

| Putting
with the LaserT
With
the LaserT
attached to the putter, align the horizontal T
line parallel to the putterface, the vertical T
line should then overlap on the target line. If you
keep the vertical T
line overlapping the target line throughout the stroke,
the putter head will travel along a perfect putting
arc (inside to inside path) with proper face rotation
(face square to the path). The best feature of the
LaserT
for putting is its straight line laser alignment technology.
Any golfer of any ability level is going to be able
to learn the proper putting stroke by simply using
the LaserT
and keeping the T
on the target line. By letting the T
point to the target line, for golfers of any skill
levels, regardless of whether you are tall or short,
the LaserT
is going to help you make a storke on a proper putting
arc with the putter face square to the arc every time
(Figure 6 and video 1)
you
can also attach the LaserT
to your hat using the metal clip, turn it on and align
the T
on the ground. The horizontal T
line should point to the target, the vertical T
line should point towards your feet to achieve and
maintain a good putting setup, including stance, ball
position and alignment. ball placement. If you maintain
a stady head during your putting stroke, the T
on the ground remains still as you stroke the ball
to the hole. If you stroke properly the putter head
should stay the putting arc as you watch the T
stay on the ground (Video 2).

LaserT
application for Chipping and pitching
Golf
swing is the rotation of your body coiled around
the swing axis based on the power house. After a
golfer completing initial set up (grip, stance,
alignments) , as shown in Figure 7, the entire body
forms two axes connected by the power house: the
lower body forms the balance axis, the up body forms
the swing axis, where the hip is the power house
which connects the balance and swing axes. During
the back swing, golfer's arms take the club, rotates
the shoulders, then the hip to swing the club to
the top; the entire body is coiled around the swing
axis like a spring; during down swing, golfer rotates
his hip, then shoulders, then arms along the swing
axis to carry the club back to the set up position
to hit the ball into the projected target. When
a golfer has correct grip, and initial setup, his
swing power is determined by the stability of the
balance and stability of the swing axis.
|
<
An
optimum golf club swing occurs when the swing axis
remains steadyl, while the golf club is rotating
with the golferĄ¯s arms and body along a plane centered
around the swing axis that allows the golfer to
execute his back swing and down swing within the
plane. The golferĄ¯s head is the hub of the swing
axis.
However,
a golfer is unaware of his head movement during
a golf club swing. There is no device that allows
a golfer to see himself during his swing. With the
LaserT
attached to the head, the golfer will decipher the
visual information feedback of the T
as it moves along the ground. The T
acts like a video camera allowing the golfer to
watch himself during the swing. If the golfer is
able to hold his head still to keep the swing axis
steady, the T
will move very little. By monitoring and analyzing
the path of movement of the T
in real time, golfer can identify his swing faults
and make instantaneous real time corrections to
overcome such faults.

Attach
the LaserT
to your hat using the metal clip, turn it on and
align the T
on the ground. The horizontal T
line should point to the target, the vertical T
line should point towards your feet to show the
ball placement. The goal is to keep the T
on the ground as stady as possible to make sure
your head remains still as you turn and swing through
the shot. If you swing properly the club head should
stay online as you watch the T
stay on the ground
Same
as chipping, attach the LaserT
to your hat using the metal clip, turn it on and
align the T
on the ground. The horizontal T
line should point to the target, the vertical T
line should point towards your feet to show the
ball placement. The goal is to keep the T
on the ground as steady as possible to make sure
your head remains still as you downswing to impact.
A still head is critical to your improvement with
pitching the ball.
