  3. Why does a golf ball have dimples? • Golf balls used to be made of leatherand 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

  4. 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
