1 The physics of putting
The dynamics of a ball rolling along level and inclined surfaces has been modeled by Domenech et al. [6] and Witters and Duymelinck [7]. In general, both the ball and the surface on which it rolls become slightly deformed and this is the source of the retarding force that acts on the ball. The force

Spinning ball in an airflow Bernoulli’s Effect nuclear
Bernoulli’s Effect Spinning ball in an airflow. The Bernoulli’s effect has another interesting interesting consequence. Suppose a ball is spinning as it travels through the air. As the ball spins, the surface friction of the ball with the surrounding air drags a thin layer (referred to as the boundary layer) of air with it.It can be seen from the picture the boundary layer is on one

Classical mechanics Wikipedia
Classical mechanics is a physical theory describing the motion of macroscopic objects, from projectiles to parts of machinery, and astronomical objects, such as spacecraft, planets, stars, and galaxies.For objects governed by classical mechanics, if the present state is known, it is possible to predict how it will move in the future (determinism), and how it has moved in the past (reversibility).
