Research draft, second pass

A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description

Let an agent explain propulsion and its methods across transport modes, compare propulsion systems, describe the physics of thrust, and support engineering and learning questions.

The action of driving or pushing an object forward by converting energy into thrust, as in vehicles moved by engines, propellers, jets, rockets, sails, pedals and electric or ion thrusters, and in animals by muscles; propulsion covers land, water, air and space transport and is studied in engineering and biomechanics, with helper locomotives and pusher engines as railway examples.

What it is for: Driving objects forward.

It can be explain propulsion methods; compare systems; describe thrust physics; support learning.

Distinguishing features

Thrust generation

Energy conversion

Mode-specific methods

Efficiency trade-offs

What it looks like

Not physical as a concept; engines, propellers, jets and thrusters.

How it is recognised

Energy converted into forward motion

Many methods by mode

Steering and braking control motion rather than drive it
