how do we define thrust?
A thrust is a force which pushes or drives a body forward or upwards. The force applied to an airplane that moves it forward or the impulse force driving the rocket upward are two examples of thrust.
then how do we exactly differentiate between thrust and pressure?
Pressure is the amount of force (acting perpendicular to the surface area) per unit area.\[P =\frac{ F }{ A }\]
how do we know that\[P =\frac{ F }{ A }\]? I MEAN HOW DO WE GET IT
Like I said Pressure is the magnitude of force per unit of area, where the force F applied is perpendicular to the surface area A.
