Smart Problem-Solving Techniques

** 30-Second Solution Methods**

Dimensional Analysis Quick Check

= Video: [3:45] - Dimensional Analysis for Quick Verification

 When to Use:
" Multiple choice questions with options in different units
" Complex formula-based problems
" Time pressure situations (last 5 minutes of exam)

 Technique:
1. Identify fundamental dimensions [M], [L], [T], [A], [K], [mol]
2. Check dimensional consistency of formula
3. Eliminate dimensionally incorrect options

Example Application:
Question: Find time period of simple pendulum with length L and acceleration g
Options: (a) 2(L/g) (b) 2(g/L) (c) 2(L/g) (d) 2(g/L)

Dimension Check:
" Time period [T] = ([L]/[L/T]) = ([T]) = [T] 
" Option (a): ([L]/[L/T]) = [T] 
" Option (b): ([L/T]/[L]) = [1/T] 
" Options (c), (d): Direct dimension check fails

Special Values Method

= Video: [4:20] - Special Values Technique for Quick Answers

 When to Use:
" Algebraic expressions with variables
" Trigonometry problems
" Limit-based questions

 Technique:
1. Substitute simple values (0, 1, /2, etc.)
2. Calculate result for each option
3. Match with expected physical behavior

Example Application:
Question: Find work done by force F = kx from x = 0 to x = a
Options: (a) ka/2 (b) ka/3 (c) ka (d) 2ka/3

Special Value Test:
Let k = 1, a = 1
W = + x dx = [x/3] = 1/3
Check options with k = 1, a = 1:
(a) 1/2  (b) 1/3  (c) 1  (d) 2/3

Quick Percentage Calculations

= Video: [3:30] - Mental Percentage Tricks for Physics

 Applications:
" Efficiency problems
" Error calculations
" Percentage change questions

 Mental Math Rules:
" 10% = Divide by 10
" 5% = Half of 10%
" 1% = Divide by 100
" 2% = Double of 1%
" 20% = Double of 10%
" 25% = Quarter (divide by 4)

Example: Calculate 17% of 200
10% = 20
5% = 10 (half of 20)
2% = 4 (double of 1%)
17% = 20 + 10 + 4 = 34

Scientific Notation Mastery

= Video: [4:15] - Scientific Notation Speed Techniques

 Applications:
" Large number calculations
" Unit conversions
" Order of magnitude estimates

 Quick Rules:
" 10  10P = 10zP
" 10  10P = 10{P
" (10)P = 10P
" Move decimal: 2.3  10 = 2300
" Move decimal: 4.5  10{ = 0.045

Speed Example: (3  10x)  (2  10{u)
= 3  2  10x{u
= 6  10
= 6000
