🌈 Pressure Rainbow Mind Map

🔴 Definition

• Pressure is force acting per unit area.
• It tells how concentrated a force is.

🟠 Formula

• Pressure = Force ÷ Area
• P = F / A

🟡 SI Unit

• Pascal (Pa)
• 1 Pa = 1 N/m²

🟢 Area Effect

• Smaller area gives more pressure.
• Larger area gives less pressure.

🔵 Force Effect

• More force gives more pressure.
• Less force gives less pressure.

🟣 Daily Examples

• Sharp knife cuts easily.
• School bag straps are broad.
• Snow shoes have large area.

⚫ Fluid Pressure

• Liquids exert pressure.
• Pressure increases with depth.

🧠 Key Point

• Pressure depends on both force and area.
• Same force can give different pressure.

Force

Contact Area

Area is large, so pressure is lower.

Pressure = Force ÷ Area

P = F / A

Important: For the same force, pressure increases when area decreases.

Pressure

Pressure is force acting per unit area.

✅ Pressure Quiz

Select the correct answer and click submit to check your score.

1. Pressure is: Force per unit area Mass per unit time Distance per unit time

2. Formula of pressure is: P = F/A P = A/F P = F × A

3. SI unit of pressure is: Pascal Newton Metre

4. 1 Pascal is equal to: 1 N/m² 1 m/N 1 kg/m

5. For the same force, pressure increases when area: Decreases Increases Becomes infinite

6. A sharp knife cuts easily because: Small area gives high pressure Large area gives low pressure It has no force

7. Broad bag straps reduce: Pressure Mass Time

8. Pressure in liquid increases with: Depth Colour Shape of container only

9. Snow shoes have large area to: Reduce pressure Increase pressure Increase weight

10. More force on same area gives: More pressure Less pressure No pressure

🧠 HOTS Questions

Click each question to reveal the answer.

1. Why does a sharp needle pierce cloth easily?

A sharp needle has a very small contact area, so it produces high pressure with little force.

2. Why are school bag straps made broad?

Broad straps increase contact area and reduce pressure on the shoulders.

3. Why do camels walk easily on sand?

Camels have broad feet, which increase area and reduce pressure on sand.

4. Why are dams thicker at the bottom?

Liquid pressure increases with depth, so dams need thicker bases to withstand greater pressure.

5. How can the same force create different pressure?

The same force creates higher pressure on a smaller area and lower pressure on a larger area.
