$\huge\mathcal\orange{Thrust:}$

▶Force exerted by an object perpendicular to the surface is known as thrust.

▶You may have noticed that when you submerge something in water it appears to weigh less. If you have gone swimming , you feel like your weight has reduced. This is because any fluid applies an upward force on a body submereged in it.

▶This force is called thrust.It is in the opposite direction to the force of gravity. Hence, it reduces the total force acting downwards due to gravity on the object and you feel like your weight is reduced.

Thrust=Pressure × Area

$\huge\mathcal\orange{Pressure:}$

▶Pressure is defined as force per unit area.

▶As you blow up a balloon, it becomes harder to blow the balloon, it becomes bigger and bigger. This is because the air pressure inside the balloon is increasing.

▶In fluids this pressure is always perpendicular to the surface of an object . It is the pressure that is applied on an object submerged in water that forms the thrust force.

▶Pressure is expressed in N/m^2 which is also known as Pascal(Pa).

Pressure = Thrust/Area

Also,

1 Pascal(Pa) = 1 Newton(N) / 1 metre square(m^2)
