In hockey, P1 typically refers to the first player in a designated power-play unit or the primary puck-carrier in a specific tactical system. It is a coaching shorthand used to organize player roles and positioning during a man-advantage.
In golf, “bounce” and “roll” describe how the clubhead interacts with the ground and how the ball behaves after impact. Bounce relates to the angle of the club’s sole, while roll refers to the ball’s forward movement on the fairway after landing. Understanding both terms helps players select equipment and shape shots.
