Thrust

• If the force is applied on a surface in a direction perpendicular to the surface, the force is called thrust
• the force acting normally on a surface is called thrust.
• A body, when placed on a surface, exerts a thrust on the surface equal to its own weight
• The unit of thrust is the Newton (N) or the kilogram force (kgf), gram force (gf
• 1 kgf = 1000 gf

  1 kgf = 10 N

  1 N = 100 gf
• The effect of thrust depends on the area of the surface on which a thrust acts
• Smaller the area of the surface on which the thrust acts, the greater the force
