What is the force acting on a unit area of a surface called?
Pressure
Pressure is defined as the force acting perpendicularly on a unit area of a surface.
Mathematically, Pressure = Force / Area, and its SI unit is the pascal (Pa), equal to one newton per square metre.
Weight is the gravitational force on a body, and Work is the product of force and displacement, so neither describes force per unit area.
Hence, the correct answer is Pressure.
