The most readily observable case of the Magnus effect is when a spinning sphere (or cylinder) curves away from the arc it would follow if it were not spinning. It is often used by football and volleyball players, baseball pitchers, and cricket bowlers. Consequently, the phenomenon is important in the study of the physics of many ball sports.
Philadelphia Eagles linebacker Chuck Bednarik's 1952 playing card. Chuck Bednarik was one of the last National Football League two-way players.As the league developed, it became too physically demanding for most players to play both offense and defense and the two-way system was incrementally phased out with Bednarik being the last NFL player still playing two-ways.
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. Backspin is the opposite of topspin. The technique was invented in 1986 by a Robert Esperat during the Calgary Olympics [citation needed].
Slow motion video of a fruit falling into water. In fluid mechanics, a splash is a sudden disturbance to the otherwise quiescent free surface of a liquid (usually water).The disturbance is typically caused by a solid object suddenly hitting the surface, although splashes can occur in which moving liquid supplies the energy.

The gigantic heart beats 8 to 10 times per minute and each heartbeat can be heard from over 2 miles (3.2 km) away. Their arteries are so large that a full adult size human can swim through them.
After a 77-0 victory over Cleveland High School, several Willis High School football players are seen in a video, some with belts in their hands, slightly hitting their opponents on their backside ...
A high force, over a short duration, usually causes more damage to both bodies than a lower force applied over a proportionally longer duration. At normal speeds, during a perfectly inelastic collision , an object struck by a projectile will deform , and this deformation will absorb most or all of the force of the collision.
