2. Bouncing ball - Wikipedia

   en.wikipedia.org/wiki/Bouncing_ball

   A bouncing ball. The motion is not quite parabolic due to air resistance. The physics of a bouncing ball concerns the physical behaviour of bouncing balls, particularly its motion before, during, and after impact against the surface of another body. Several aspects of a bouncing ball's behaviour serve as an introduction to mechanics in high ...

3. Magnus effect - Wikipedia

   en.wikipedia.org/wiki/Magnus_effect

   The Magnus effect, depicted with a backspinning cylinder or ball in an airstream. The arrow represents the resulting lifting force. The curly flow lines represent a turbulent wake. The airflow has been deflected in the direction of spin. The topspinning cylinder "pulls" the airflow up and the air in turn pulls the cylinder down, as per Newton's ...

6. Reynolds number - Wikipedia

   en.wikipedia.org/wiki/Reynolds_number

   Under the condition of low Re, the relationship between force and speed of motion is given by Stokes' law. [24] At higher Reynolds numbers the drag on a sphere depends on surface roughness. Thus, for example, adding dimples on the surface of a golf ball causes the boundary layer on the upstream side of the ball to transition from laminar to ...

7. Golf ball - Wikipedia

   en.wikipedia.org/wiki/Golf_ball

   A golf ball is a ball designed to be used in golf. Under the rules of golf, a golf ball has a mass no more than 1.620 oz (45.9 g), has a diameter not less than 1.680 inches (42.7 mm), and performs within specified velocity, distance, and symmetry limits. Like golf clubs, golf balls are subject to testing and approval by The R&A (formerly part ...
