Now as I understand, golf balls have dimples to help improve distances and reduce turbulence. I may be wrong but I think it requires spin to increase distance over a smooth ball but the stability against turbulence I’m not so sure.
So where my question appeared was recently I was throwing stones at the ocean, there was lots of wind straight into my face so I was slinging against the wind. I found that the smooth stones I threw were not as far as the slightly rough stones. The shapes were very similar as were weights(just as an estimate) but the surface of the stones were different.i was getting the smooth stones closer to the water and the rough ones from the shore.
So really I want to know if there’s anyone that understands the dynamics involved a little better than me, is it because the stones are relatively light for the surface area , Magnus effect, lift? Or would this also happen with lead glandes??
You're wrong.
Mythbusters tested this myth with dimpled cars (without spinning them) and found the car with dimples was more fuel efficient.
Spin in rocks, golfballs, and baseballs creates drag and lift. This can turn a thrown object (i.e. curveball or slice) or help you throw farther if orientated correctly (backspin). I don't know of any experiments confirming this, but the laces on a baseball are supposed to help with that so golfball dimples and rough stones likely have the same effect.
My first guess would be that the rocks that are travelling further are likely slightly more dense than the other rocks. You might not be able to tell the difference in your hand.
One way or another, you're imparting more force to one kind of rock.
