Why does a golf ball have dimples?

• Golf balls used to be made of leather and stuffed with feathers

• They then started making smooth balls out of rubber or wood

• Golfers began to notice that the ball went a greater distance when it had been used a few times

• The used balls had scratches, nicks and bumps• This lead golf ball makers to start purposely putting

dimples on the balls so they would travel further

Why does a golf ball have dimples?

• The dimples give the ball different flight characteristics– A smooth ball actually creates more drag because

the way it travels through the air– The ball with dimples is able to reduce the

amount of drag caused by the air
