FAQs
1. What is the physics behind a golf swing?
The physics behind a golf swing involves the principles of force, motion, and energy transfer. The golfer uses their muscles to apply force to the golf club, which in turn transfers energy to the golf ball. The angle and speed of the clubhead, as well as the spin and trajectory of the ball, are all determined by the physics of the swing.
2. How does the ball’s trajectory change based on the angle of the clubface?
The ball’s trajectory changes based on the angle of the clubface at impact. A closed clubface (where the handle is tilted toward the ground) will produce a lower, draw shot, while an open clubface (where the handle is tilted away from the ground) will produce a higher, fade shot. The spin rate of the ball also affects its trajectory, with more spin resulting in a higher, more stable shot.
3. How does the weight distribution of the golf club affect the swing?
The weight distribution of the golf club affects the swing by determining the balance and stability of the club. A golf club with a higher balance point will provide more stability and control during the swing, while a lower balance point will allow for a more fluid, natural swing.
