Propulsion: meaning, definitions and examples

Generally used in a technical or scientific context to refer to the force that moves an object forward.

• The propulsion system of the rocket was tested thoroughly.
• Advancements in propulsion technology have improved the efficiency of modern aircraft.

Used similarly to 'propulsion' but more often in descriptive language, focusing on the action of driving something forward.

• The motor is propelling the boat through the water.
• Strong winds were propelling the sailboat faster than expected.

Typically used in everyday language to describe the act of controlling a vehicle or motivating a person or situation.

• She is driving to work right now.
• What are the driving factors behind this decision?

Occurs more in formal or literary contexts, signifying a force that compels or urges forward action or motion, often with a sense of urgency.

• A sense of duty was impelling him to act.
• Her words had an impelling effect on the audience.

Typically used in scientific and technical contexts to describe the act of driving or pushing forward, especially in the context of vehicles or objects moving through a medium like air or water.

• The ship's propulsion system was upgraded for better efficiency
• The airplane relies on jet propulsion to achieve sustained flight

Can be used both in literal and figurative contexts. Literally, it refers to the power causing movement. Figuratively, it implies the motivation or reason behind an action or trend.

• Electric engines have become the driving force behind the new generation of cars
• Her passion for education is the driving force behind her success

Commonly used in aerodynamics and space contexts to describe the force applied to move an object forward. It can also be used in more everyday language to describe vigorous effort or push.

• The jet engines provide the necessary thrust for takeoff
• He thrust his hand into the box to find the hidden key

Used similarly to 'propulsion,' often in technical or mechanical contexts to describe the capability of pushing or moving an object forward.

• The rocket's propelling power was tested before its launch
• Engineers are working on increasing the propelling power of the new drones

Used when discussing the general concept of making something move, especially in engineering or physics.

• The new rocket design improved the propulsion efficiency.
• Marine engineers are working on innovative propulsion systems for ships.

Used when specifically referring to the process of producing thrust, which is essential for propulsion, especially in aviation and rocketry.

• Thrust generation in modern jet engines involves the compression and ignition of air.
• Rocket scientists are testing new fuel types to improve thrust generation.

Used when discussing the power or energy required for flight, often in the context of aviation.

• The jet engine provides the necessary flight power for the aircraft.
• Engineers are researching alternative sources of flight power to reduce emissions.

Used when describing the motion or maneuvering of an aircraft.

• Air traffic controllers monitor aircraft movement to ensure safety.
• Weather conditions can significantly affect aircraft movement.
