Propulsion is the act of pushing or driving an object forward. It is a term used in many fields, including physics, engineering, and aerospace. The term can be broken down into five distinct solutions: FORCE (5 letters), PUSH (4 letters), IMPULSE (7 letters), IMPETUS (7 letters), and ROCKET (6 letters). FORCE is the application of a physical influence on an object, while PUSH is the act of applying pressure to an object in order to move it. IMPULSE is a sudden, strong urge or desire to do something, while IMPETUS is a FORCE that motivates or encourages action. Finally, ROCKET is a vehicle that is propelled by a ROCKET engine, which uses the FORCE of combustion to create thrust.
