I’ve got a couple questions about the Sweet spot on a golf club, I’m hoping someone may have some answers. I’m not sure if this should go in Club Techs or Equipment, I apologize if it’s in the wrong place. Anyways, back to my questions.

Why is the “Sweet Spot” of a club the SS of the club?

Why does that spot feel the best when struck there?

Why does that spot produce the max Ball Speed?

Why do off center strikes feel worse and produce less ball speed?

How does moving weight around in a club head make the SS larger?

Where does the weight need to be moved to make the SS larger?

Is the area that produces max ball speed actually made larger, Or is it just a larger area that produces “near” max ball speeds and there is still a small area that produces Max ball speed?

How does moving the weight around in a club head change the feel of a center strike?

Why do they need to manipulate “feel” in club heads? If the sweet spot is larger, shouldn’t the club feel better on its own?

Hopefully some of you fine fellas have some answers, if not thanks anyways for stopping by.  Also Thanks to anyone who does have some answers, I appreciate any info you have on the subject :)

This kind of feels like a test!

Why is the “Sweet Spot” of a club the SS of the club?  

It is centre of gravity of the club, the point where no energy is wasted due to angular deflection.

Why does that spot feel the best when struck there?

Maximum energy transfer, no twisting, optimum resonance vibration.

Why does that spot produce the max Ball Speed? As above

Why do off center strikes feel worse and produce less ball speed?

The club face is deflecting, so there is a reduction in energy transfer efficiency. The deflection produces unwanted vibration.

How does moving weight around in a club head make the SS larger?

This helps the head resist the deflection (a little) when missing the sweet spot.

Where does the weight need to be moved to make the SS larger?

round the perimeter of the head.

Is the area that produces max ball speed actually made larger, Or is it just a larger area that produces “near” max ball speeds and there is still a small area that produces Max ball speed?

The sweet spot is still the same size, the penalty for missing it is reduced. Manufacturers use thin variable thickness faces and cup face designs to help maintain ballspeed over a larger area.

How does moving the weight around in a club head change the feel of a center strike?

Mass behind impact is reduced.

Why do they need to manipulate “feel” in club heads?

A lot of the technology used above produces unpleasant impact vibration frequencies which have to be dampened to make impact feel somewhat satisfying to the player.

If the sweet spot is larger, shouldn’t the club feel better on its own?

As above the use of thin faces, stronger hotter faces produce harsher resonance frequencies which need to be managed.

Thank you very much for the info Sir!! I didn’t expect to get so many answers right off the bat like that. :)
