Propel

Propel is a verb that means to drive, push, or cause something to move forward. It is used in a wide range of contexts, from physical objects being moved by force to abstract ideas that drive action or progress.

Etymology traces propel to the Latin pro- meaning forward and pellere meaning to drive or push. In English, propel commonly describes initiating motion or maintaining forward movement, such as propelling a bicycle with pedaling or propelling a spacecraft with thrust.

In physics and engineering, propulsion refers to the act or method of generating thrust to move a body, such as a vehicle or aircraft. Propulsion systems convert energy into kinetic energy or momentum, and they can operate by expelling reaction mass (rocket propulsion) or by pushing against a surrounding medium (propeller or jet propulsion). Thrust, momentum transfer, and energy efficiency are central considerations in propulsion design and analysis.

Propel is also the name of an open-source software project, specifically a PHP Object-Relational Mapping (ORM) framework. Propel provides tools for mapping PHP objects to relational database tables, generating code, and managing database schema and migrations. It supports multiple database systems and is used to simplify data access and persistence within PHP applications, alongside other ORM solutions.

In commerce, Propel is used as a brand name for various consumer products, reflecting a sense of forward motion or advancement. The term’s versatility allows it to appear in contexts ranging from technology and science to marketing and branding.
