PHYSICS WITH MANDELA📚

💡 INTRODUCTION 💡

📚 Pressure is defined as Force acting normally in a unit area. It is given as

📖 Pressure in solids 📖

Pressure= Force/Area

From this relationship, it is obvious that Pressure is directly proportional to Force and pressure is inversely
proportional to the Area.
.....................

🔘The unit of pressure of Newton per Meter squared.
🔘Pressure has the same S.I unit as stress.
🔘 The main units of pressure are the pascal and Newton per Meter squared (N/m²)

P = F/A
F = W = mg

P = mg/A 👍✅ 📚

⭐Pressure in solids depends on the force exerted and area of the body.

⭐Pressure on a body increases with an increase in force acting on it i.e P ∝ F.

⭐Pressure decreases with an increase in area 📖
P ∝ 1/A

📖Hence, a man standing on one toe of his foot (small area) exerts a larger pressure compared to a man standing on both feet😅

📖Cutting objects with sharp knifes (small area) exerts a great pressure.


The units for pressure and their relationship: 📖
 
📖 1Pascal(Pa)=1𝑁m-²
📖 1Bar=10⁵𝑁m-² =10⁵Pa. 
📖 1mmHg = 1Torr
📖 760mmHg =1Atmosphere(Atm).
