What physics are involved in golf
Mech_Engineer said:"All of physics" is pretty general, and probably not accurate.

The angle of the club at impact plays a crucial role in determining the trajectory of the golf ball. A steeper club angle will result in a higher trajectory, while a shallower angle will result in a lower trajectory. This is because the angle of the club determines the amount of backspin on the ball, which affects its lift and therefore its trajectory.
Spin is a major factor in determining the distance a golf ball will travel. Backspin, which is created by the grooves on the face of the club, helps the ball stay in the air longer, resulting in a longer carry distance. Additionally, spin can also affect the roll of the ball once it hits the ground, with more backspin resulting in less roll and more sidespin causing the ball to curve off course.
Velocity, or the speed of the golf club head at impact, is a key factor in determining the distance and accuracy of a golf shot. A faster club head speed can result in a longer carry distance, while a slower speed may result in a shorter shot. Additionally, velocity can also affect the spin and trajectory of the ball, so it is important for golfers to control their club head speed for optimal performance.
Air resistance, or drag, can have a significant impact on a golf ball's flight. As the ball moves through the air, it experiences both laminar and turbulent flow, which can cause changes in its trajectory and spin. Additionally, the dimples on a golf ball are designed to reduce drag and allow for a more predictable flight path.
The golf swing is a great example of the laws of motion in action. The first law, or the law of inertia, states that an object will remain at rest or in motion unless acted upon by an external force. In golf, this is seen when the club head is at rest before being swung by the golfer's force. The second law, or the law of acceleration, states that the acceleration of an object is directly proportional to the force applied and inversely proportional to its mass. In golf, this is seen when the golfer applies force to the club to accelerate it and hit the ball. The third law, or the law of action and reaction, is seen when the golfer's force on the club creates an equal and opposite reaction on the ball, causing it to be propelled forward.
