Tale of the Tape
A guide to understanding the physics of impact
Using pressure activated impact tape, we are able to view the "fingerprint" of the exact moment of impact between the golf club and the ball.
By studying the appearance of the tape after impact, we can determine many things about the shot and also the swing which once defined can help us make the necessary changes to the swing or the club in order to improve the condition of impact.
Definitions:
- Club Head Speed: The physical speed in miles per hour that the club head is moving at the exact point of impact. NOTE: Centeredness of hit will influence club head speed where a centered hit will slow the club head down more than an off centered hit. (see smash factor) Although only one factor in determining distance, Swing speed can be thought of as being compared with horsepower of an engine or quantitatively describing potential for power output. The more clubhead speed, the greater potential there is for distance.
- Ball Velocity: The physical speed in miles per hour that the golf ball is traveling post impact.
- Launch Angle: The physical angle at which the golf ball is launched from the club head.
- MOI: Moment of inertia: The moment of inertia of an object about a given axis describes how difficult it is to change its angular motion about that axis. For example, consider two discs of the same mass, one large and one small in radius. Assuming that there is uniform thickness and mass distribution, the larger radius disc requires more effort to accelerate it (i.e. change its angular motion) because its mass is effectively distributed further from its axis of rotation. Conversely, the smaller radius disc takes less effort to accelerate it because its mass is distributed closer to its axis of rotation. Quantitatively, the larger disc has a larger moment of inertia, whereas the smaller disc has a smaller moment of inertia.
- Swing Path: The direction relative to the target line that the club head is moving through the impact area.
- Swing Plane: The angle relative to the spine angle the shaft of the golf club is traveling through the downswing and into the impact area.
- Angle of attack: The angle relative to the center of gravity of the body at which the golf club is delivered into the impact area.
- Smash Factor: Ball velocity divided by swing speed. A “theoretically perfect” smash factor is 1.50, but a driver is able to deliver much higher smash factors due to the trampoline effect of the club face.
- Centeredness of hit: Location relative to center where the ball impacted the clubface.
- Clean vs Dirty Impact:
- Clean impact implies that there was very little frictional loss at impact between the club and the ball. This can be identified by the appearance of a clear dimple pattern on the face tape at impact.
- Dirty impact implies that there was significant frictional loss at impact between the club and the ball. This can be identified by the appearance of a “smudged” dimple pattern on the face tape at impact.
