ABC - American Bowling Congress

AMF - Owns and operates hundreds of Bowling Centers in the United States and around the world. Headquartered in Richmond, Virginia.

Anchor - Last bowler in the lineup of a team normally one of the better bowlers on the team.

Approach - Section of the lane situated behind foul line which allows one to pick up momentum before delivery.

Armadillo - Clear plastic device for determining a bowler's positive axis point. Device has a series of lines on it, which are matched up to a bowler's initial track. When the device is aligned with the ball track, the device points to the bowler's axis point.

Arrows - Marks implanted in the lane which begin approximately fifteen feet past the foul line that serve as reference points when directing the ball.

Axis of rotation - (example, 0, 45, and 90 degrees) This is a measure of the direction of the initial rotation on the ball with respect to the lane. It is a measurement of the angle between the initial spin axis and the foul line running across the lane. A zero degree axis of rotation is all forward roll. The rotation on the ball is in the direction of the forward travel. The rotation will help keep the ball in the initial direction. The ball will not hook very much. It will roll out early. Therefore, a bowler with this style will need balls drilled to go long. A 90-degree axis of rotation is all side roll. The rotation is perpendicular to the initial direction. The rotation is trying to make the ball hook at a 90-degree angle to the initial direction. This gives the ball more potential to hook. This style causes the ball to skid further down the lane and then hook more. A bowler with this style will most likely need balls drilled to hook earlier; such as, axis weight or pins closer to their axis.

Axis tilt - (example, a spinner versus a full roller): This is a measure of the angle of the initial spin axis to a horizontal plane. A full roller or high track style would have little or no axis tilt. The initial spin axis would be parallel or close to parallel with the lane surface. One rotation of the ball would cover the major diameter of the ball. A spinner would have an initial spin axis tilted up from the lane. The ball track would be far away from the thumb and finger holes. One rotation of the ball would cover a much smaller diameter then other bowlers. The spinner style will get the ball further down the lane before it hooks.

Axis weight - Axis weight is a drilling pattern designed to produce little or no track flare and get the ball into an early roll with little backend reaction. Axis weight has the pin located on or near the bowler's PAP. The core is positioned along the initial spin axis. This places the core in a stable position. The ball will be initially rotating about the minimum RG axis, which is a stable core position. Therefore, it will continue to rotate about this axis creating no track flare. This reduces the backend reaction. Since the ball is rotating about the low RG axis it is easier for the bowler to rotate it off their hand which gets the ball into an earlier roll.
