On this shot, the ball is hit higher on the clubface with more direct impact than the skid spinner. The ball stops quickly on the green because of its steep landing angle, not its backspin. For Cameron's 30-yard flop shot, the backspin (S) is only 4,100 revolutions per minute, but the launch angle is up to 51 degrees. The ball speed is similar to that for the 30-yard skid spinner, even though the club's velocity (V) is much faster. The reason is simple: More energy is going into hitting the ground with the bounce of the club to create a slightly upward angle of attack on the ball.
