8.2.A—Describe the pressure exerted on a surface by a given force

Describe the pressure exerted on a surface by a given force.

• Pressure is defined as the magnitude of the perpendicular force component exerted per unit area over a given surface area, as described by the equation
• Pressure is a scalar quantity.
• The volume and density of a given amount of an incompressible fluid is constant regardless of the pressure exerted on that fluid.
