Question 23

Why does a longer golf club generally result in a longer drive, assuming the same swing force is applied?

Accepted Answer

A longer club increases the radius of the swing, resulting in greater linear velocity at the clubhead.

Answer

Newton's third law states that for every action, there is an equal and opposite reaction, thus increasing the impact force.

Answer

A longer club increases the time the clubhead is in contact with the ball, resulting in greater momentum transfer.
