2. Bouncing ball - Wikipedia

   en.wikipedia.org/wiki/Bouncing_ball

   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 school or undergraduate level physics courses.

3. File:Newton's Law of Motion Soccer Diagram.pdf - Wikipedia

   en.wikipedia.org/wiki/File:Newton's_Law_of_Motion...

   In the second law, the ball is being kicked causing its acceleration to be dependent on the mass of the soccer ball and the net force of the kick. In the third law, a player is performing a header on the ball. When the ball hits the player's head, there is an equal and opposite reaction allowing for the ball to bounce off the player's head.

4. Magnus effect - Wikipedia

   en.wikipedia.org/wiki/Magnus_effect

   Topspin in ball games is defined as spin about a horizontal axis perpendicular to the direction of travel that moves the top surface of the ball in the direction of travel. Under the Magnus effect, topspin produces a downward swerve of a moving ball, greater than would be produced by gravity alone.

5. Ball (association football) - Wikipedia

   en.wikipedia.org/wiki/Ball_(association_football)

   A football or soccer ball is the ball used in the sport of association football. The ball's spherical shape, as well as its size, weight, mass, and material composition, are specified by Law 2 of the Laws of the Game maintained by the International Football Association Board . [ 1 ]

6. Truncated icosahedron - Wikipedia

   en.wikipedia.org/wiki/Truncated_icosahedron

   The balls used in association football and team handball are perhaps the best-known example of a spherical polyhedron analog to the truncated icosahedron, found in everyday life. [14] The ball comprises the same pattern of regular pentagons and regular hexagons, each of which is painted in black and white respectively; still, its shape is more ...

7. Coefficient of restitution - Wikipedia

   en.wikipedia.org/wiki/Coefficient_of_restitution

   A bouncing ball captured with a stroboscopic flash at 25 images per second: Ignoring air resistance, the square root of the ratio of the height of one bounce to that of the preceding bounce gives the coefficient of restitution for the ball/surface impact. In physics, the coefficient of restitution (COR, also denoted by e), can be thought of as ...

8. Curl (association football) - Wikipedia

   en.wikipedia.org/wiki/Curl_(association_football)

   The ball is struck with the inside of his right foot, with his body leaning to the left to generate extra curl on the ball. Curve or bend in association football is a definition for a spin on the ball which makes the ball move in a curved direction. When kicking the ball, the inside of the foot is often used to curl the ball, but this can also ...

9. Backspin - Wikipedia

   en.wikipedia.org/wiki/Backspin

   In sports, backspin or underspin refers to the reverse rotation of a ball, in relation to the ball's trajectory, that is imparted on the ball by a slice or chop shot. Backspin generates an upward force that lifts the ball (see Magnus effect). [1] While a normal hit bounces well forward as well as up, backspin shots bounce higher and less forward.
