If you have gone swimming, you feel as though your weight has reduced. This is because any fluid applies an upward force on a body submerged in it. This force is called thrust. This force is in the opposite direction to the force of gravity. Hence, it reduces the total force acting downwards due to gravity on the object and you feel as though your weight has reduced. Pressure Pressure is defined as the force per unit area. If a force F is applied on a surface of area A, then the pressure P is defined as: \(\begin \) As you blow up a balloon, it becomes harder to blow the balloon as it becomes bigger and bigger. This is because the air pressure inside the balloon is increasing. P...

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 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: 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. Categories Post navigation
