How is pressure defined in terms of force and area?
Pressure is the force acting normally (at 90 degrees) per unit length of a surface.
Pressure is the force acting normally (at 90 degrees) per unit area of a surface.
Pressure is the force acting parallel (along the surface) per unit area of a surface.
Pressure is the mass acting normally (at 90 degrees) per unit area of a surface.
