Question:
In golf, how is momentum affected by different angles of different clubs?

Hi, Josh,

If you use a club with a larger angle so the ball starts out moving a larger angle above the horizontal, the force the club exerted on the ball is clearly at a larger angle above the horizontal. Then, by Newton's second law (For every action (force), there is an equal and opposite reaction) the ball exerts a more downward force back on the club. Since the club cannot move much vertically (if it is held firmly in the hands of the golfer), the effective horizontal component of the force of the ball back on the club will be reduced so the momentum of the club is reduced by a smaller amount. The ball also receives a smaller component of momentum forward and so does not travel as far.

Does this answer your question? I'm not sure which momentum you are asking about, If you still have questions, please try again,

Best, Dick Plano, Professor of Physics emeritus, Rutgers University
