Answer 2

Answer:

Thrust” is same as force, but since “force” is overused, “thrust” is used to describe a force in certain situations.

Ships, submarines, airplanes and rockets move because something within them applies thrust.

Car engines do not apply thrust. They apply “torque” to some wheels (nowadays usually the front two).

Pressure, of course, is a well defined science term; even some IAS aspirants may know this (just think of Boyle’s Law and Charles’ Law from school). But soon they graduate to “political pressure”, and that is the only pressure they know for the rest of their mundane, uninspiring lives.
