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 ...
Armadillo Aerospace's quad rocket vehicle showing shock diamonds in the exhaust plume from its propulsion system. 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.

Mechanical heat engines convert heat into work via various thermodynamic processes. The internal combustion engine is perhaps the most common example of a mechanical heat engine in which heat from the combustion of a fuel causes rapid pressurisation of the gaseous combustion products in the combustion chamber, causing them to expand and drive a ...
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 ...
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]
Under existing road traffic legislation, the use of an e-scooter on public roads is not permitted. According to the Road Traffic Act 1961, all e-scooters are considered to be "mechanically propelled vehicles". Anyone using a mechanically propelled vehicle in a public place must have insurance, road tax, and a driving license.
A motor vehicle, also known as a motorized vehicle, automotive vehicle, automobile, or road vehicle, is a self-propelled land vehicle, commonly wheeled, that does not operate on rails (such as trains or trams), does not fly (such as airplanes or helicopters), does not float on water (such as boats or ships), and is used for the transportation ...
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.
