Pressure (P): The force per unit area is called pressure.
The SI unit of pressure is Pascal (Pa).
Pressure (P) = Force (F)/ Area (A)
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.
The effect of thrust is more on the smaller surface area than the thrust acting on a larger surface area.
