What is "poncelet"

Poncelet \Ponce"let\, n. [After Jean Victor Poncelet, French engineer.] (Physics) A unit of power, being the power obtained from an expenditure of one hundred kilogram-meters of energy per second. One poncelet equals g watts, when g is the value of the acceleration of gravity in centimeters.

n. An obsolete French unit of power, equal to the power required to raise a quintal at a velocity of one metre per second.

Poncelet may refer to:

• Poncelet, a unit of power formerly used in France
• Christian Poncelet (1928– ) conservative French politician
• Jean-Victor Poncelet (1788–1867), French engineer and mathematician
• Thierry Poncelet (1946- ), Belgian painter known for his dog portraits
• Poncelet Prize, a mathematics prize by the French Academy of Sciences
• Matthew Poncelet, the character played by Sean Penn in the 1995 film Dead Man Walking, based on real-life death-row inmate Elmo Patrick Sonnier
• French submarine Poncelet, a Vichy French submarine sunk off the coast of Gabon during the World War II Battle of Gabon

Poncelet is the remains of a lunar crater that is located near the northern limb of the Moon. It lies to the east-northeast of the crater Pascal and northwest of Anaximenes. Like the latter formation, Poncelet is a worn, eroded formation with an interior that has been flooded, either with lava or possibly ejecta. The outer rim is a low, circular ridge with a narrow break to the south and a wider breach to the northeast. The interior floor is pock-marked with many tiny craterlets, the most notable of which is Poncelet H, located just to the southeast of the midpoint.

The poncelet (p; named after Jean-Victor Poncelet) is an obsolete unit of power, once used in France and replaced by cheval vapeur (cv, metric horsepower). The unit was named after Jean-Victor Poncelet.

One poncelet is defined as the power required to raise a hundred-kilogram mass ( quintal) at a velocity of one metre per second (100 kilogram-force·m/s).
