Outrageously Funny Word Dictionary :: Propulsions

👉 Propulsion is a process by which an object moves. It can be achieved through a variety of means, including mechanical, chemical or biological processes. Propulsion can include the transfer of energy from one part of an object to another, such as via engines or motors. In the context of propulsion, there are two main types: internal combustion and external combustion. Internal combustion occurs when an object is heated by a fuel source, such as gasoline or diesel fuel, which then ignites in a combustion chamber
