Golf Ball Physics

Golf Balls Have dimples on their surfaces to minimize drag (a force that dissipates when an object moves through a fluid).

A smooth ball causes the air to flow in such a way that the air “sticks” to the ball longer. The dimples also act to create backspin- which makes the air pressure on the top of the ball decrease- giving it lift (somewhat like the situation with an airplane’s wings).

A smooth ball that ravels 65 meters would travel something like 275 meters with dimples when hit with the same force.

Golf balls have 300-500 dimples that can be 0.25 mm deep.
