Question

plzz tell me ,difference between thrust and pressur

Answer 1

Thrust and Pressure

Thrust : Force exerted by an object perpendicular to the surface is called thrust.

Pressure : Force exerted by any object per unit area is called pressure.

∴Pressure=ForceArea∴Pressure=ForceArea

Or, Pressure=ThrustAreaPressure=ThrustArea

Or, p=FAp=FA ---(i)

Where, p is pressure, F is thrust or force and A is the surface area of the object.

Since, pressure is indirectly proportional to the surface area of the object, thus, pressure increases with decrease in surface area and decreases with increase in surface area.

Answer 2

The total force acting normally on surface in contact is called thrust.
The thrust acting upon a unit area of surface is called pressure.

Thrust is independent of the nature of the surface on which it acts.
Pressure depends on the softness of the surface on which thrust acts.

The SI unit of thrust is Newton (N)
And SI unit of pressure is pascal (Pa)

Hope this helps you.
