Difference between force and pressure

The difference between force and pressure is that “Force is an agency which moves or tends to move ,stops or tends to stop the motion of a body.Force is the vector quantity.While pressure is the force acting normally per unit area on the surface of a body.It is a scalar quantity.

Relation between pressure and force

Mathematically ,pressure can be written and calculated as:

Pressure = Force/Area

P =F/A

It means greater will be the force greater will be the pressure.
