Thrust - Wikipedia
Thrust - Wikipedia

Thrust, is a reaction force described quantitatively by Newton's third law.When a system expels or accelerates mass in one direction, the accelerated mass will cause a force of equal magnitude but opposite direction on that system. The force applied on a surface in a direction perpendicular or normal to the surface is also called ,thrust,. Force, and thus ,thrust,, is measured using the ...
