Arc width belongs to which category in the PGA swing model?

• A. Principles
• B. Ball flight law
• C. Preferences
• D. Timing

Answer: (A)

Arc width describes a structural guideline about how wide the swing arc should be, a fundamental aspect of how the body and arms move together through the swing. In the PGA swing model, such universal, repeatable aspects of motion fall under Principles because they dictate the way the swing is built and how its geometry is maintained. Ball flight laws, by contrast, are about the physics of the ball after impact—launch, spin, and trajectory—outcomes of the swing rather than the mechanics of the swing itself. Preferences refer to individual likes or feels, which are subjective and vary from player to player. Timing concerns when parts of the swing occur, such as tempo and transition, rather than the static structure of the swing arc. So arc width belongs to Principles because it’s a foundational mechanical guideline that shapes the swing’s shape and consistency, not the physics of ball flight, personal taste, or the timing of the swing.
