Post swing pose for golfer Henry Cotton in 1931. The golf swing is the action by which players hit the ball in the sport of golf. 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.

A hybrid is a type of club used in the sport of golf with a design borrowing from both irons and woods while differing from both. The name "hybrid" comes from genetics to denote a mixture of two different species with desirable characteristics of both, and the term here has been generalized, combining the familiar swing mechanics of an iron with the more forgiving nature and better distance of ...
In traditional units, it measures fuel consumption in pounds per hour divided by the brake horsepower, lb/(hp⋅h); in SI units, this corresponds to the inverse of the units of specific energy, kg/J = s 2 /m 2.
The batteries that Tesla uses in their electric cars deliver about 254 W⋅h/kg, [1] compared to supercapacitors that are typically rated between 3 and 10 W⋅h/kg, [2] with the best commercially available supercapacitors as high as 47 W⋅h/kg. [3] Nuclear batteries based on betavoltaics can reach up to 3300 W⋅h/kg, although over much longer ...
For example, Concorde cruised at 1354 mph, or 7.15 million feet per hour, with its engines giving an SFC of 1.195 lb/(lbf·h) (see below); this means the engines transferred 5.98 million foot pounds per pound of fuel (17.9 MJ/kg), equivalent to an SFC of 0.50 lb/(lbf·h) for a subsonic aircraft flying at 570 mph, which would be better than even ...
Capacities of such units are given in Nm 3 /h, normal cubic meters per hour, one Nm 3 /h being equivalent to 1000 liters per hour under any of several standard conditions of temperature, pressure, and humidity. for nitrogen: from 100 Nm 3 /h at 99.9% purity, to 9000 Nm 3 /h at 97% purity; for oxygen: up to 1500 Nm 3 /h with a purity between 88% ...
