What is Pascal’s Law? | Definition, Formula, Examples – Hydrostatics

Pascal’s Law Definition:
The increase in pressure at a point in the enclosed liquid in equilibrium is transmitted equally in all directions in liquid and to the walls of the container.

We are giving a detailed and clear sheet on all Physics Notes that are very useful to understand the Basic Physics Concepts.

What is Pascal’s Law? | Definition, Formula, Examples – Hydrostatics

The working of hydraulic lift and hydraulic brakes are based on Pascal’s law.

Pascal’s Law Formula:

F = PA

F is the force applied
P is the pressure transmitted
A is the cross-sectional area

Pascal’s Law Examples:
One of the most common examples of Pascal’s Law is the hydraulic braking system present in the automobiles. Every time you see a car come to a halt.

Pascal’s law finds numerous examples in our daily life such as

  • Automobiles.
  • Hydraulic brake system.
  • Hydraulic jack.
  • Hydraulic press.
  • Hydraulic machines.

Hydrostatics is a property of liquid or fluid in mechanics. A fluid is a material which flows at room temperature, because its upper molecule overlaps the inner molecule, which tends to flow the liquid in forward direction. In hydrostatics, we will learn about the condition of fluids when it is in rest or exerted by an external force. Here we will study the fluids in motion.
