Question

write at least three to four points of difference between thrust and pressure

Answer 1

Difference between thrust and pressure are
Thrust:
1.The force exerted by the body perpendicular to the surface is known as thrust.
2.SI 34 unit of thrust is newton (N)
Pressure:
1.Thrust acting on unit area is called pressure, i.e.
Pressure § = Force / Area (A)
2.SI 34 unit of pressure is ${{Nm}^{2}}$ or Pa (pascal).
(ii) The pressure exerted by 1 N of force, acting perpendicular on the surface of 1 m2 area is called 1 pascal.
1Pa = 1${{Nm}^{-2}}$
The force required to accelerate 1 kilogram of mass at the rate of 1 metre per second square is called 1 newton.
IN = 1${{Kgm}^{-2}}$
Since, pressure is inversely proportional to the area of contact.
Therefore, pressure will reduce to half, if area of contact is doubled.
