Description: Bowling ball spin-up (with horizontal speed-reduction) between black dots i.e. a delivery that starts the ball in a skid which evolves into a roll. After spin-up the speed levels out as static-friction takes over, which in turn may allow side-roll to hook the ball into the pins. This provides a practical and visceral example of (i) angular-acceleration accompanied by translational-deceleration, (ii) kinetic versus static friction, as well as (iii) the rolling-constraint. The frame-residuals also make screen-captures useful for practicing Bayesian inference of a ball's properties from observational data.
