单词	newton
释义	newton noun new·​ton ˈnü-tᵊn  ˈnyü- : the unit of force in the meter-kilogram-second system equal to the force required to impart an acceleration of one meter per second per second to a mass of one kilogram Example Sentences Recent Examples on the Web The tiny, spinning silica ball can measure torque down to a quadrillionth of a newton-meter, or about 750 trillion pound-feet. Caroline Delbert, Popular Mechanics, 17 Feb. 2020 If the ball has a mass of 1 kilogram, the gravitational force would be 9.8 newtons. Rhett Allain, Wired, 5 Feb. 2020 The gravitational interaction is a constant force pointing toward the center of the planet, with a magnitude equal to your mass times the gravitational field (which is 9.8 newtons per kilogram on Earth). Wired, 6 Sep. 2019 Their teeth and jaw are quite a nasty duo, with a great white shark has the bite power of nearly 17,790 newtons (about 4,000 pounds per square inch). Erin Davis And Katherine Dillinger, CNN, 14 July 2019 Measurements showed the thrusters collectively generated five newtons for each kilowatt of power, which is actually similar to the output of jet engines. John Timmer, Ars Technica, 21 Nov. 2018 With these in place, the micro-drones can pull well above their 100-gram weight, exerting 40 newtons of force or enough to lift four kilograms (about eight pounds). James Vincent, The Verge, 24 Oct. 2018 The gray polymer shell, which partially conceals aircraft-grade aluminum, seems too skinny to support his weight; the ankle, too delicate for the 10,000 newtons of force it was built to withstand. Erik Sofge, Popular Mechanics, 28 May 2012 Collectively, these generate 22.8m newtons of thrust—about as much as eighteen 747 jetliners.
