Metre per second squared - Wikipedia, the free encyclopedia Metres per second squared is the SI derived unit of acceleration (scalar) and (vector), defined by distance in metres divided by time in seconds and again divided by time in seconds. The SI derived unit of force, the newton, is equal to one "kilogram metre per second squared", meaning that a force of one newton is needed to give an acceleration of one metre per second squared to a mass of one kilogram. This is an illustration of Newton's second law (see Newton's laws of motion) in its simplest form, where acceleration is defined as the rate of change of velocity. en.wikipedia.org /wiki/Meter_per_second_squared   (171 words)

Meter Christian Huygens, an astronomer, suggested that one meter should equal the length of a pendulum with a period of one second. Other scientists argued that the meter should be one ten-millionth of the length of the Earth's meridian (a line of longitude) along one of its quadrants (Fig. Even though the meter is the standard SI measurement of length, it would be pretty difficult to measure something as small as a plant cell or as big as the diameter of the sun with just a meter stick. www.jracademy.com /~ewotawa/MeterM.html   (579 words)

Re: Can you warm a cup of coffee by stirring it? If the cup of coffee has about 175 grams of water (a reasonable size for a cup of coffee), then 1 calorie of "heat" would raise the temperature by only 1/175 degree Celcius (The definition of a "calorie" is "the amount of 'heat' needed to raise one gram of water by one degree Celcius".). A Joule is the amount of work done by a force of one Newton acting for one meter (the force being assumed to be in the same direction as the motion). Power is equal to force times velocity, so the power we can stir at is roughly 1/10 Newton times 1/4 meter per second, or roughly 1/40 Watt (a Watt is a Newton meter per second). www.madsci.org /posts/archives/nov2001/1006378049.Ph.r.html   (489 words)

New Scientist Breaking News - Scientists reveal the secret of cuddles The revelation came after doctors realised that a woman with no sense of touch still felt a "pleasant" sensation when her skin was caressed. Normal touch is transmitted to the brain through a network of fast-conducting nerves, called myelinated fibres, which carry signals at 60 metres per second. But there is a second slow-conducting nerve network of unmyelinated fibres, called C-tactile (CT), the role of which was unknown. www.newscientist.com /news/news.jsp?id=ns99992598   (513 words)
