These vehicles are propelled by at least one electric motor. [1] [2] Good example is an electric locomotive that is drawing power directly from overhead wire or third rail. "Electric vehicle" is often cleverly interchanged with "Electrified vehicle" [3] which doesn't specify what kind of powertrain vehicle actually has. Electric vehicles do not ...
Propulsion is the generation of force by any combination of pushing or pulling to modify the translational motion of an object, which is typically a rigid body (or an articulated rigid body) but may also concern a fluid. [1] The term is derived from two Latin words: pro, meaning before or forward; and pellere, meaning to drive. [2]
Vehicle dynamics is the study of vehicle motion, e.g., how a vehicle's forward movement changes in response to driver inputs, propulsion system outputs, ambient conditions, air/surface/water conditions, etc. Vehicle dynamics is a part of engineering primarily based on classical mechanics.
While paddles and sails are still used on some smaller boats, most modern ships are propelled by mechanical systems consisting of an electric motor or internal combustion engine driving a propeller, or less frequently, in pump-jets, an impeller. Marine engineering is the discipline concerned with the engineering design process of marine ...
Jet propulsion is produced by some reaction engines or animals when thrust is generated by a fast moving jet of fluid in accordance with Newton's laws of motion.It is most effective when the Reynolds number is high—that is, the object being propelled is relatively large and passing through a low-viscosity medium.
A magnetohydrodynamic drive or MHD accelerator is a method for propelling vehicles using only electric and magnetic fields with no moving parts, accelerating an electrically conductive propellant (liquid or gas) with magnetohydrodynamics. The fluid is directed to the rear and as a reaction, the vehicle accelerates forward. [1] [2]
A vehicle (from Latin vehiculum) [1] is a machine designed for self-propulsion, usually to transport people, cargo, or both.The term "vehicle" typically refers to land vehicles such as human-powered vehicles (e.g. bicycles, tricycles, velomobiles), animal-powered transports (e.g. horse-drawn carriages/wagons, ox carts, dog sleds), motor vehicles (e.g. motorcycles, cars, trucks, buses, mobility ...
railway vehicle for carrying goods; can be open ("a coal truck") or covered ("a cattle truck") – cf. s.v. wagon: any of various vehicles for carrying esp. things or animals, as a forklift truck or a pickup truck. metal part of a skateboard which connects the wheels to the deck and acts as an axle.
