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 ...
Classical mechanics is the branch of physics used to describe the motion of macroscopic objects. [1] It is the most familiar of the theories of physics. The concepts it covers, such as mass, acceleration, and force, are commonly used and known. [2]
If a template uses {{Infobox person/weight|{{{weight}}}|kg-stlb=yes}}, then an article using that template with an input in kg will display two conversions: lb followed by st/lb (default is one conversion to lb): |weight=100 kg → 100 kg (220 lb; 15 st 10 lb) |weight=108–111 kg → 108–111 kg (238–245 lb; 17 st 0 lb – 17 st 7 lb)
Sporting bullets, with a calibre d ranging from 4.4 to 12.7 millimetres (0.172 to 0.50 in), have C b in the range 0.12 lb/in 2 to slightly over 1.00 lb/in 2 (84 kg/m 2 to 703 kg/m 2). Those bullets with the higher BCs are the most aerodynamic, and those with low BCs are the least.

If the velocity of the jet from a jet engine is equal to sonic velocity, the jet engine's nozzle is said to be choked. If the nozzle is choked, the pressure at the nozzle exit plane is greater than atmospheric pressure, and extra terms must be added to the above equation to account for the pressure thrust.
