When we walk on sand we leave our foot prints in the sand. This is due to the weight of our body which acts normal to the surface of contact - the foot and sand. Similarly when we want to stick a picture in a scrap book we apply a force normal to the surface of the paper. Such force acting normally on a surface is called thrust . Thus, the net force acting normal to a surface is called thrust .  Thrust is a vector quantity . Definition of thrust Thrust - Total force acting perpendicular to the surface. Unit of thrust Si unit of thrust : newton (N) C.G.S unit of thrust : dyne Thrust is also expressed in kgwt or gwt or kgf. 1 kgwt = 9.8 N 1 gwt = 980 dynes

Thus, the net force acting normal to a surface is called thrust .  Thrust is a vector quantity . Definition of thrust Thrust is the force exerted in a specific direction by a propulsive system, such as an engine or rocket. It opposes resistance and propels an object forward, commonly associated with vehicles like airplanes, rockets, or vehicles with engines. In physics, it is a vector quantity measured in units like Newtons (N). Units of thrust In the International System of Units (SI), thrust is measured in Newtons (N) . In the Centimetre-Gram-Second (CGS) system , it is measured in dyne (dyn). Other units include pound-force (lbf) in the Imperial syst...
