3 FORCES AND PRESSURE 3.1 UNDERSTANDING PRESSURE 1. Define Pressure 2. State pressure’s formula Pressure is force per unit area Pressure = Force Area P= F A The SI unit : Nm-2 = Pascal = Pa The pressure of a given force increases as the surface area decreases. 3. State relationship between pressure and area. 4.
Pressure is the ratio of the force applied to the area over which it is exerted. A solid in contact with a fluid experiences a force all over its outer surface. chaos
12 wrz 2022 · When the pressure inside the tank is greater than atmospheric pressure, the gauge reports a positive value. Some gauges are designed to measure negative pressure. For example, many physics experiments must take place in a vacuum chamber, a rigid chamber from which some of the air is pumped out.
