			In a mechanical system, such as a rocket, an [[engine]] or [[turbine]] will do [[work]] to send gas molecules downwards. By Newton's Third Law, a force will be felt in the '''opposite direction''' of molecule travel and the system will feel a force upwards. This upwards force is thrust. (see Figure 1).<ref>NASA, ''What is Thrust?'' [Online], Available: https://www.grc.nasa.gov/www/k-12/airplane/thrust1.html</ref> Jet engines expel a [[jet]] of a fluid and the [[momentum]] of that jet pushes the object forward.
