  2. Vehicle classification by propulsion system - Wikipedia

    en.wikipedia.org/wiki/Vehicle_Classification_by...

    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 h

  3. Propulsion - Wikipedia

    en.wikipedia.org/wiki/Propulsion

    There are many different methods. Each method has drawbacks and advantages, and spacecraft propulsion is an active area of research. However, most spacecraft today are propelled by forcing a gas from the back/rear of the vehicle at very high speed through a supersonic de Laval nozzle. This sort of engine is called a rocket engine.

  4. Magnetohydrodynamic drive - Wikipedia

    en.wikipedia.org/wiki/Magnetohydrodynamic_drive

    Illustration of the right-hand rule for the Lorentz force, cross product of an electric current with a magnetic field. The working principle involves the acceleration of an electrically conductive fluid (which can be a liquid or an ionized gas called a plasma) by the Lorentz force, resulting from the cross product of an electric current (motion of charge carriers accelerated by an electric ...

  5. Vehicle - Wikipedia

    en.wikipedia.org/wiki/Vehicle

    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 ...

  6. Personal transporter - Wikipedia

    en.wikipedia.org/wiki/Personal_transporter

    That does not mean that personal transporter is legal. The Transport Department issued a 2015 statement that under the Road Traffic Ordinance, a personal transporter is classified as motor vehicle, since it is mechanically propelled. [57] Registration and licence is required before any motor vehicle is used on the roads, including private roads.

  7. Vehicle dynamics - Wikipedia

    en.wikipedia.org/wiki/Vehicle_dynamics

    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.

  8. Propeller - Wikipedia

    en.wikipedia.org/wiki/Propeller

    The principle employed in using a screw propeller is derived from stern sculling.In sculling, a single blade is moved through an arc, from side to side taking care to keep presenting the blade to the water at the effective angle.

  9. Energy efficiency in transport - Wikipedia

    en.wikipedia.org/wiki/Energy_efficiency_in_transport

    Chevrolet Volt in full electric mode uses 36 kilowatt-hours per 100 miles (810 kJ/km; 94 mpg‑e), meaning it may approach or exceed the energy efficiency of walking if the car is fully occupied with 4 or more passengers, although the relative emissions produced may not follow the same trends if analysing environmental impacts.
