The velocity of sliding between two mating gear surfaces is the relative velocity at their point of contact and can be calculated as the sum of their angular velocities multiplied by the distance between the pitch point (where the gears theoretically touch without slipping) and the actual point of contact. This accounts for the difference in speed between the two surfaces at the contact point, leading to sliding.
