Pressure
Pressure: When you press down the handle of a bicycle pump, the pressure of air within the pump increases and this in turn inflates the bicycle tyre. When you push the handle of a bicycle pump you apply a force on the surface area of its piston. So, the effect of a force also depends on the area of the object over which it works. “This effect of force on a given area is called Pressure.” Thus, we conclude that pressure depends on two factors:
1. Force applied and
2. Area over which force acts.
Pressure is the force per unit area. Pressure = Force/ Area
