Mnemonics: Physical World And Units & Measurements | Physics Class 11 - NEET PDF Download

MNEMONICS are powerful tools to simplify complex physics concepts and make learning easier.

 This edurev document provides creative and concise mnemonics to help  students quickly grasp and recall key topics.  Use them to make your study sessions more efficient and effective! Happy Learning!

1.  Physical World

Mnemonic: "Good Workers work for Extended Session"

Explanation:

• Good: Gravitation
• Workers: Weak Nuclear Force
• Extended: Electromagnetism
• Session: Strong Nuclear Force

Strength wise arrangement of fundamental forces in ascending order:
Gravitation < Weak Nuclear Force < Electromagnetism < Strong Nuclear Force

The order should be learn as can be asked in conceptual based questions.

2. Seven Fundamental Quantities

Mnemonic: "Let My Time Always Keep Me Calm"

Explanation:

• Let: Length - Metre (m)
• My: Mass - Kilogram (kg)
• Time: Time - Second (s)
• Always: Electric Current - Ampere (A)
• Keep: Thermodynamic Temperature - Kelvin (K)
• Me: Amount of Substance - Mole (mol)
• Calm: Luminous Intensity - Candela (cd)

Helpful in solving dimensional analysis questions.

3. Systems of Units

Mnemonic: "Can Frogs Make Sandwiches?"

Explanation:

• C - CGS System (Centimeter, Gram, Second)
• F - FPS System (Foot, Pound, Second)
• M - MKS System (Meter, Kilogram, Second)
• S - SI System (International Standard System)

4. Applications of Dimensional Analysis

Mnemonic: "Daring Cats Climb Down"

Explanation:

• Daring - Derive relationships
• Cats- Check correctness of equations
• Climb - Convert units
• Down - Deduce formulas

A method for solving all the numericals of dimensional analysis.

5. Two Supplementary Units

Mnemonic: "Ravi Smiles"

Explanation:

• Ravi - Radian (Plane Angle)
• Smiles - Steradian (Solid Angle)

6. Scientific Notation

Mnemonic: "Power Saves Time!"

Explanation:

• Use powers of 10 to represent very large or small numbers concisely.
