| 释义 | kinetic energy (once / 34359 pages) n Kinetic energy is the kind of energy an object has because it's in motion. Speeding cars and hyper children have a lot of kinetic energy. According to physics, kinetic energy is one of many types of energy that exist. This is energy generated because something is moving — the faster it's going, the more kinetic energy it has. A person sitting has no kinetic energy, but a person running like a maniac has tremendous kinetic energy: if they run into you, you'll feel the brunt of it. Footballs, baseballs, rocks, bullets, airplanes, and anything else moving quickly through the air all have kinetic energy. WORD FAMILYkinetic energy: kinetic energies USAGE EXAMPLESDeformations of the soft substrates within a few microseconds of impact absorbed the drops' kinetic energy, decreasing splashing. Nature(Nov 01, 2016) He found that kinetic energy — a combination of mass and speed — was the best predictor of how efficiently an arrow penetrated the gel. New York Times(Oct 31, 2016) Superfluidity is a similar state that is achieved when liquids flow with no viscosity at all, meaning no loss of kinetic energy as they move.
