The motion of a bouncing ball obeys projectile motion. [2] [3] Many forces act on a real ball, namely the gravitational force (F G), the drag force due to air resistance (F D), the Magnus force due to the ball's spin (F M), and the buoyant force (F B). In general, one has to use Newton's second law taking all forces into account to analyze the ...
A superball or power ball is a bouncy ball composed of a type of synthetic rubber (originally a hard elastomer polybutadiene alloy named Zectron) invented in 1964, which has a higher coefficient of restitution (0.92) than older balls such as the Spaldeen so that when dropped from a moderate height onto a level hard surface, it will bounce nearly all the way back up.
Tracer elements separating from M2 Browning.50 BMG machine gun rounds after hitting the target or backstop.. A ricochet (/ ˈ r ɪ k ə ʃ eɪ / RIK-ə-shay; French:) is a rebound, bounce, or skip off a surface, particularly in the case of a projectile.
The COR is a property of a pair of objects in a collision, not a single object. If a given object collides with two different objects, each collision has its own COR. When a single object is described as having a given coefficient of restitution, as if it were an intrinsic property without reference to a second object, some assumptions have been made – for example that the collision is with ...
An object hitting a surface is an example of deflection. Deflection is a change in a moving object's velocity, hence its trajectory, as a consequence of contact with a surface or the influence of a non-contact force field.

Other terms include "cooler" in the U.S. [2] and "door supervisor" in the U.K. [3] In U.S. bars, "cooler" is often the term for the head bouncer. [4] The "cooler" is expected to have the same ability to respond to physical situations as the rest of the bouncers, but should also have reliable interpersonal skills that can be used to de-escalate situations without violence.
