What is the SI unit of thrust?

CONCEPT:

• Thrust: The force acting perpendicular to the surface of the object is called thrust.
  • When any object is put into the water then the object will replace the water the same as it’s volume and the cause of which there is a force acting upwards, to balance this weight is called the thrust force.
  • Thrust is a kind of pull force, which is applied by the medium on the object.
  • It is a type of force so the SI unit of thrust is Newton (N).
  • The effect of thrust is more on the smaller surface area than the thrust acting on a larger surface area. 

Thrust Force (F_T) = Pressure (P) × Area (A)

EXPLANATION:

• The SI unit of thrust is Newton. So option 4 is correct.
• The SI unit of pressure is the pascal.
• The SI unit of momentum is kg-m/s.
• The SI unit of surface tension is N/m.

​EXTRA POINTS:

• Inertia- It is a kind of resistive force of any object to change its state.
• Momentum- When any massive object moving with a certain velocity, then the momentum of that object will be multiplication of the mass and velocity. The SI unit is kg-m/s
• Volume-It is the quantity of three-dimensional space enclosed by a closed surface.
