The speed of a Bullet (Handgun) is about 1,260 feet per second.
(for .40 Smith & Wesson 135 grain Sierra JHP, VV 3N37 powder, Fed. 100 primer, Remington case) (muzzle velocity)
A 0.40 caliber Smith & Wesson bullet has a muzzle a velocity of 1,260 feet per second. This type of ammunition has been the standard issue round of the United States Federal Bureau of Investigation (FBI) since 1990.
It's about one-five-hundredth as fast as a Jet Fighter
The speed of a Jet Fighter is about 2,200 feet per second.
(for Lockheed Martin F-16, a.k.a. Fighting Falcon, a.k.a. Viper) (maximum speed at altitude)
An F-16's maximum speed at altitude is approximately 2,200 feet per second. The F-16 has a flight ceiling of approximately 15 km (9.32 mi).
It's about one-six-hundred-fiftieth as fast as a Bullet (Rifle)
The speed of a Bullet (Rifle) is about 3,000 feet per second.
(5.56 x 45 mm, a.k.a. 5.56 NATO)
A 5.56 x 45 mm cartridge is fired at a velocity of 3,000 feet per second. As the NATO rifle cartridge, it is used by the military forces of more than thirty-one countries, including use in the M16 series, M4 Carbine, HK-416, and M249 Squad automatic weapons used by the United States armed forces.
It's about one-five-thousand-five-hundredth as fast as The Space Shuttle
The speed of The Space Shuttle is about 25,406 feet per second.
(Orbiter vehicle velocity)
The space shuttle orbits at a speed of 25,406 feet per second. During liftoff, the space shuttle accelerates to orbital speed in 8.5 minutes, consuming over 1.59 million kg (3.51 million lbs) of propellant in the process.
It's about one-thirty-thousandth as fast as a Meteor
The speed of a Meteor is about 140,000 feet per second.
(formally Meteoroid or meteorite, depending on the context; a.k.a. "shooting star", a.k.a. "falling star")
Small meteoroids enter the Earth's atmosphere at speeds between 36,000 feet per second and 240,000 feet per second, depending on their size. The fireball effect, known as ablation, ceases once the atmosphere has slowed the meteoroid to a velocity of about 9,100 feet per second.
It's about one-seventy-thousandth as fast as a bolt of Lightning
The speed of a bolt of Lightning is about 320,000 feet per second.
(atmospheric electrical discharge)
A bolt of lightning can travel at up to 320,000 feet per second when arcing from the atmosphere to the Earth. An estimated 280 million lightning strikes strikes occur each year.
It's about 35,000,000 times as fast as Grass growing
The speed of Grass growing is about 0.000000130 feet per second.
(for Kentucky Bluegrass, Poa pratensis) (a.k.a. Smooth Meadow grass, a.k.a. Common Meadow grass) (Summer months, ideal growing conditions)
Kentucky Bluegrass, one of the most common grasses in North America, grows about 0.000000140 feet per second in the summer months under ideal conditions. When left un-mowed, Kentucky Bluegrass grows to heights of 60 to 90 cm (2 to 3 ft) and blossoms with a blue flower.
It's about 0.000000005 times as fast as The Speed of Light
The speed of The Speed of Light is about 983,571,056.430450 feet per second.
(C) (in a vacuum)
The speed of light (and all other electromagnetic radiation) in a perfect vacuum is known as "c" and measures 983,571,056.430450 feet per second, per the formal definition of the meter. While visible light travels close to this speed in air, it slows to 655,714,037.631230 feet per second when passing through the glass of a typical window.
