Question

propulsion n.推进；推进力 (1) 这架飞机是喷气推进的。(2) 鱼靠尾鳍在水中前进。(3) 此时无推进力产生。(4) 这是电磁推进力的基本原理。 The noun propulsion came from the Latin prōpellere, "to push away." The modern meaning of propulsion meaning "the act of moving forward" was first recorded in 1799. In water, flippers, fins, and the wind can aid propulsion. In a general sense, if society is to move forward, we must stop using fossil fuels as our main means of propulsion.
