Putt Physics Calculation 08: Aiming direction

golf

First, look at this image.

The green slopes 0.5° from above to below the gray line, and the putt is made from a distance of 3 meters around the cup (black circle).

At the time I heard this story, it was hard for me to believe it, but when I tried it on the practice green, I found it to be true. Please give it a try.

However, there is a condition. That is, the area around the cup must be flat. In this example, if there are undulations on the green surface within the 3-meter circle, the red circle will be shifted when undulations are involved. Isn’t there such an ideal condition on a real green? You may think, “But in reality, you only play from the spot where your ball is, so if the area around the cup is flat, such as a semicircle or a quarter circle, you can find the red circle by the same concept. In professional tournaments on TV, the cups are often placed in difficult positions, such as near the tiers of double-tiered greens or around the snake line, but on greens for amateurs, the cups are often placed on flat areas, although there is a slope. In other words, the “Putt Physics” calculation is useful.

Now, calling it a “gray line” or a “red circle” is not very appealing, so we call it this way in the “Putt Physics” application.

Elevation line:
Gray line. It is an imaginary line connecting the lowest and highest points of the green. It is assumed that the player stands at the lowest point, so it is a straight uphill line.

Lespaul:
If the slope is less than 1°, putt in the direction of Les Paul and you will get a cup. Les Paul is an anagram of “Special Unique Point at Elevation Line”.

There is always one of these poles on the elevation line, which is determined by the distance and slope angle.
