🌈 Mass Rainbow Mind Map

🔴 Definition

• Mass is the amount of matter present in a body.
• It tells how much substance an object contains.

🟠 Type

• Mass is a fundamental physical quantity.
• It is a scalar quantity.

🟡 Units

• CGS unit → gram (g)
• FPS unit → pound (lb)
• SI unit → kilogram (kg)

🟢 Standard Relations

• 1 kg = 1000 g
• 1 g = 1000 mg
• 1 lb ≈ 453.59 g

🔵 Larger Units

• quintal
• metric tonne
• used for heavy objects

🟣 Smaller Units

• gram
• milligram
• used for small quantities

🟤 Measuring Devices

• Beam balance
• Grocer’s balance
• Physical balance
• Electronic balance

⚫ Important Point

• Mass remains constant everywhere.
• Weight changes with gravity, but mass does not.

🧠 HOTS Questions

Click each question to reveal the answer.

1. Why does mass remain constant everywhere?

Mass depends on the amount of matter in an object, which does not change from place to place.

2. Why is kilogram used as SI unit of mass?

Kilogram is internationally accepted as the standard SI unit of mass.

3. Why do we use milligram?

Milligram is used to measure very small quantities, such as medicine or chemicals.

4. Why is a balance used to measure mass?

A balance compares an unknown mass with a known standard mass.

5. How is mass different from weight?

Mass is the amount of matter, while weight is the force due to gravity acting on that mass.
