Difference between Thrust and Pressure? | Physics | Don't Memorise

TL;DR

Thrust is the total force acting perpendicular to a surface, while pressure is the force per unit area.

Transcript

Think about most of the forces you see in Daily life You're pushing a box your weight. Which is a force acting downwards, hammering a big nail into the ground. All these forces, if you notice, are acting perpendicular to the surface A force exerted by an object perpendicular to the surface is given a special name. It's called Thrust. It's the total...

Key Insights

• 🧑‍🏭 Thrust is the total force acting perpendicular to a surface.
• 🇦🇪 Pressure is the force per unit area and is inversely proportional to the area.
• ❓ Thrust and pressure are related concepts in physics.
• ❓ The depth or depression caused by pressure depends on the area on which the force is applied.
• ❓ Thrust and pressure are measured in Newton and Pascal, respectively.
• 🧑‍🔬 Pascal is named after scientist Blaise Pascal.
• 🆘 Understanding the concepts of thrust and pressure helps explain various everyday phenomena.

Questions & Answers

Q: What is thrust?

Thrust is the total force acting perpendicular to a surface, such as the force exerted when pushing a box or hammering a nail into the ground.

Q: What is pressure?

Pressure is the force per unit area. It explains the difference in depression on our fingers when applying equal force to a pencil from both ends and why our feet sink deeper in loose sand compared to lying down on it.

Q: What is the SI unit of thrust?

The SI unit of thrust is the same as that of force, which is Newton. Thrust is measured in Newton.

Q: What is the SI unit of pressure?

The SI unit of pressure is Pascal, which is Newton per meter squared. It is named after Blaise Pascal, who conducted extensive studies in this scientific area.

Summary & Key Takeaways

• Thrust is the force acting perpendicular to a surface, and its unit is Newton, the same as force.

• Pressure is the force per unit area, and it is inversely proportional to the area on which the thrust is applied.

• The SI unit of pressure is Pascal, named after scientist Blaise Pascal.
