	Metre per second - Wikipedia, the free encyclopedia
		Metre per second (U.S. spelling: meter per second) is an SI derived unit of both speed (scalar) and velocity (vector quantity which specifies both magnitude and a specific direction), defined by distance in metres divided by time in seconds.
		Astronomical measurements sometimes list velocities in terms of kilometres per second, where a kilometre per second is equivalent to 1 000 metres per second.
		Although m/s is considered as a derived unit, it could be viewed as more fundamental than the metre, since the latter is defined through the speed of light in the vacuum, taken to be exactly 299792458 m/s by definition, which then gives the metre using the definition of one second.

		The preferred SI unit for velocity is m/s (metres per second), although km/h or kph is often used as a replacement for mph.
		Miles per hour is the unit used for speed limits on roads in the US and Britain.
		Kilometre per hour (American spelling: kilometer per hour) is a unit of both speed (scalar) and velocity (vector).

		Twelve hours was impossibly short because the rocket would not be able to accelerate it to a great enough speed, and sixty hours was considered too long because of battery life and equipment reliability.
		This occurred at a distance of 113,000 kilometres from the Earth.
		The cloud expanded at a rate of 1 kilometre per second, attaining a diameter of 400 kilometres before it became too faint to observe.

		The Japanese/German pairing claimed an incredible 1 hour, 52 minute and 12 second winning margin after 19 days and 5,216 kilometres of competition in an 8,552 kilometre route that has taken the crews from Marseilles in France, down to Spain, Tunisia, across Libya and into Egypt.
		This is also Masuoka's second consecutive win and he is also the first Mitsubishi driver to triumph in the event twice.
		After the opening one kilometre stage in Marseilles on New Year's Day - for which the times do not count in the overall classification - Mitsubishi Motors drivers led from start to finish, underlining the Japanese manufacturers outright superiority in the Dakar Rally and the world of off-road competition.

	SPEED IN MILES PER HOUR KILOMETERS PER HOUR AND KNOTS CONVERSION FORMULAE AND TABLES
		Miles per hour is the unit used for speed limits on roads in the U.S., Britain and various other nations including overseas territories.
		Both miles per hour and knots is a speed which is the number of units of distance that is covered for a certain amount of time.
		To do this problem easily, one can multiply the number of miles per hour that the train is moving by the number of feet per hour that = 1 mph.

	Weird Words: Solar sail
		Like so many ideas concerning space travel, this one has been in existence for decades, mostly in science-fiction stories, though it is now being thought about more seriously as new materials become available.
		The idea is that a spacecraft would unfurl a huge but incredibly thin solar sail, perhaps a kilometre in diameter.
		A craft massing several tonnes could accelerate to more than a kilometre per second within days, and then go on accelerating so long as it remained relatively close to the sun.

		Runaway stars have been seen before, but the previous record-holder was seen traveling at a mere 490 kilometers per second, and all of them are still confined in our Galaxy.
		They then mounted the sensor in a small flow-through chamber and tested its sensitivity to low concentrations of dimethyl methylphosponate (DMMP), a compound that is often used to simulate nerve agents, and nitrogen dioxide in air.
		The electrical conductance though the device increased by about 5% when it was exposed to 78 parts per billion (ppb) of DMMP in air at 500¡C and changed with the concentration of the nerve agent stimulant.

		For the second year running, Mexico has proven to be a tough event for the Citroen team and Loeb in particular.
		To stand a chance of progressing even further up the leaderboard, the challenge was simple: they needed to take 36 seconds off Harri Rovanperä and 37.4s off Toni Gardemeister over the final day's two stages which totalled 62.65 km; an average of just under half a second per kilometre.
		While the first of these two tests - Comanjilla/Chichimequillas' - was relatively short, the second - 'Alfaro/El Establo' - was quite simply the longest of the event and the organisers had programmed it at the very end with a view to keeping up the suspense all the way to the finish.

		A tip to observing, is to wait for a clear moonless night (give you eyes time to get dark-adapted) and look up at 45 degrees, try not to look/concentrate at the radiant.
		The visual strength of a meteor shower is measured by its Zenithal Hourly Rate (ZHR), defined as the number of meteors a single average observer would see if the radiant were directly overhead and the sky dark and transparent with a limiting stellar 6.5.
		Another method is the flux of a meteoroid stream, measured in numbers of meteors of absolute brightness (referenced to a range of 100 km) brighter than 6.5 per square kilometre per second perpendicular to the radiant + direction.

		In this superbubble (also called supershell) scenario the cloud's stem would be the first bubble and the cap would be identified as the second bubble.
		The theories also propose that the second bubble could possibly break apart, allowing the hot gas produced during star death to escape into the galaxy's halo.
		However the DRAO observations are the first which are detailed enough to constrain various theories and in fact challenge the details of this particular model.

		This quantifies the intuitive notion that a 1-gram bullet travelling at 1 kilometre per second, and a 1-kilogram bowling ball travelling at 1 metre per second, have something in common.

		By measuring a greater energy for the photon, our observer is also using the light as a signal to compare his or her local clock with a clock far away, and by this method, local time seems to be “running slower” by 25%.

		Also one thought was that perhaps before we began the Passive Thermal Control rotation of the spacecraft, that the area of the SIM bay where the camera was located may have become quite cold, causing the problem to occur, and perhaps causing something to freeze up and stop the camera from retracting.
		At the present time Apollo 15 is 16,668 nautical miles [30,869 km] from the Moon, and the spacecraft velocity is 3,910 feet per second [1,192 m/s].
