  • Radius of gyration, RG - Measured in inches, radius of gyration is the distance from the axis of rotation at which the total mass of a body might be concentrated without changing its moment of inertia.
  • Moment of Inertia - Resistance to change in rotation.
  • Total differential - The difference between the X (low RG) and Y (high RG) axes values of any bowling ball.
  • Intermediate differential - The difference in radius of gyration between the Y (high RG) and Z (intermediate RG) axes on the bowling ball.
