What is Thrust in Physics? | Definition, Example, Units – Hydrostatics

Thrust Physics Definition:
Total force acting perpendicular direction to the surface is called Thrust. The total normal force exerted by liquid at rest on a given surface is called thrust of liquid.

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

What is Thrust in Physics? | Definition, Example, Units – Hydrostatics

Example of Thrust in Daily Life:

  • Thrust is to move forward as a crowd entering a stadium.
  • Thrust is to force one’s self into a conversation.
  • An example of thrust is a fish being expelled from the ocean by a strong wave.
  • It is easy to carry or to walk with high heels, and cause thrust acting here (a perpendicular force).
  • A pistole engine can produces thrust on its own.

Thrust Unit:
Thrust = Force
The SI unit of thrust is newton.
The CGS unit of thrust is dyne.

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.
