Pressure is defined as the amount of force acting per unit area. It is denoted by P. Mathematically, it is expressed as
Living Science Physics Class 6 ICSE Solutions Chapter 5 Pressure - 2
Its unit is N/m2 or pascal (Pa).
Factors on which pressure exerted by a body depends are :
(i) Magnitude of force (thrust) – Greater the force, more is the pressure.
(ii) Area of contact – Greater the area of contact, lesser is the pressure.
