Α video codec is software or a device that provides encoding and decoding for digital video, and which may or may not include the use of video compression and/or decompression. Most codecs are typically implementations of video coding formats . The compression may employ lossy data compression, so that quality-measurement issues become important.
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 ...
Also called a hole in one. address The act of taking a stance and placing the club-head behind the golf ball. If the ball moves once a player has addressed the ball, there is a one-stroke penalty, unless it is clear that the actions of the player did not cause the ball to move on purpose. If the player addresses the ball and places the head of the club behind it and in doing so causes the ball ...
Golf's ruling bodies are changing the equipment testing to make sure the golf ball goes shorter for everyone from Tiger Woods to the amateur who plays public courses on the weekend. The USGA and R ...
Newton's cradle. 3-D rendering of the cradle in motion. Newton's cradle is a device, usually made of metal, that demonstrates the principles of conservation of momentum and conservation of energy in physics with swinging spheres. When one sphere at the end is lifted and released, it strikes the stationary spheres, compressing them and thereby ...
The viral video shows Ball working on her swing before a voice is heard from the neighboring bay. "Excuse me, what you're doing there — you shouldn't be doing that," the man says. "You're going ...

The golf swing is a complex motion involving the whole body; the technicalities of the swing are known as golf stroke mechanics . There are differing opinions on what constitutes a "good" golf swing. [ 1] In Work and Power Analysis of the Golf Swing, Nesbit and ...
The coefficient of restitution ( COR, also denoted by e ), is the ratio of the relative velocity of separation after collision to the relative velocity of approach before collision. It can also be defined as the square root of the ratio of the final kinetic energy to the initial kinetic energy. It normally ranges from 0 to 1 where 1 would be a ...
