We can define pressure as a force applied perpendicularly over a surface of an object. This force is then distributed over the unit area. Pressure is often expressed in units of Pascals (Pa).

**Formula to calculate pressure.**

We calculate pressure by dividing the force by area.

**Example:**

What pressure would be applied by a body that exerts a force of 100N on the table whose area is 15m².

The pressure applied by the body on the table is 6.67 Pa.
