Trajectories

The ball spins at a fixed location in the wind tunnel while the air flows past it. An alternative way to measure the Magnus force is to film the trajectory of a spinning ball using several cameras, but a lot of cameras would be needed to view at right angles to a high speed ball travelling over a distance of 50 m or more.

PGA Average Trajectories Same Height All Clubs

The trajectory that carries 200 yards is an average 5-iron trajectory for a PGA Tour player. I've marked on each trajectory the angle above the horizon as seen by the golfer during each second of flight. So, after 1 second, the 9-iron is higher but has travelled less distance (because the ball is not moving as fast as when struck with a 5-iron).

Motion Characteristics of a Projectile

Projectiles are objects upon which the only force is gravity. Gravity, being a vertical force, causes a vertical acceleration. The vertical velocity changes by -9.8 m/s each second of motion. On the other hand, the horizontal acceleration is 0 m/s/s and the projectile continues with a constant horizontal velocity throughout its entire trajectory.
