Putt Physics Calculation 02: Pendulum Width

golf

In the previous issue, we explained that the “Putt Physics” calculation assumes that the putter swing is a pendulum motion. Now that we know the velocity of the putter head just before it impacts the ball as a result of the calculation, what exactly should we do with the swing? Yes, the answer is already there. You just need to swing at an angle of θ°. … You get the idea!

The most common way to adjust putt distance is to use a swing angle, right? We use swing width as the one we suggest in the application “Putt Physics” because that is how it is explained in many magazines and videos. This choice was not too confusing, but what I was a little worried about was whether to display the angle θ° or not. Is there anyone who says that the angle display is easier for me to understand? For putts with a swing angle of more than 45°, the angle display may be easier to understand. If there are many requests for it, I may set up a function to switch the display.

Now, it is easy to calculate the swing angle from the angle θ°.

$$スイング幅=2Lsin\theta$$

Calculate this equation to find the length of the string. Since the string length is half the swing width, it is twice as long. If a person of 170 cm in height and 140 cm in string length of the pendulum swings at an angle θ = 9°, the swing width is 22 cm.

This completes the calculation of swing width.
