Rotational motion—the ultimate nightmare for average NEET aspirants like me.
No matter how many times I tried, my brain refused to rotate with the motion. The formulas spun in my head like a fidget spinner, but nothing made sense.
And then, one day, a miracle happened.
His name? Anand Kumar Sir.
A teacher so legendary that even the toppers sat straight when he entered the class.

The First Encounter: The Class Begins
I was half asleep, my notebook open to a random page, when I heard a booming voice.
"Bachcho! Rotational Motion sirf naam se tough lagta hai, asal mein yeh ek kahani hai physics ki!"
I looked up. Anand Kumar Sir had arrived.
He was in his late 40s, wore simple clothes, and had an aura of a battlefield general. His energy was unmatched.
"Aaj tumhara dimaag ghoomega… lekin tension mat lo, physics bhi ghoomega!" He laughed at his own joke, and surprisingly, so did the class.
This man had cracked the ultimate secret: teaching physics without making students cry.

The Secrets of Rotational Motion
He started with a simple question.
"Beta, tum cycle chala sakte ho?"
The class nodded.
"Agar ek bade wheel wali cycle ho aur ek chhoti wheel wali, kaunsi zyada smoothly chalegi?"
"Sir, badi wheel wali!" someone answered.
Anand Sir grinned. "Bilkul sahi! Kyunki inertia zyada hoga. Moment of inertia! Jo bada hoga, woh smoothly chalega. Bas yahi concept hai rotational motion ka!"
I blinked. Wait… that actually made sense?!
For the first time, the word ‘moment of inertia’ didn’t feel like an alien language.
Then, he explained:
Trick #1: The Pizza Analogy
"Ek garam pizza lo. Usko teen tukdo mein kaatna aasan hoga ya dus tukdo mein?"
The class murmured, “Dus tukdo mein zyada force lagega.”
"Bilkul! Agar mass door door hai, toh inertia badh jaata hai. Isliye ring ka inertia solid sphere se zyada hota hai. Kyunki mass door hai! Bas yahi hai moment of inertia ka funda."
BOOM.
My brain processed it in one go.

Trick #2: The Door vs. Hinge Trick
"Kabhi darwaza dhakka maara hai?"
"Sir, roz maarte hain," someone joked.
The class laughed. Anand Sir grinned.
"Agar darwaza beech se dhakka maaro ya kone se, kya fark padega?"
"Sir, kone se zyada force lagega!"
"Wahi toh! Distance badhne se torque badhta hai. Torque \= Force × Distance. Darwaza physics ka best example hai!"
At that moment, I realized—Rotational Motion wasn’t hard. It was just explained badly before.

Study Made Fun: Anand Sir's Special Techniques
Storytelling Method – Every concept was a real-life example. He made Physics feel alive.
Hand Movements & Expressions – He acted like a door, a bicycle wheel, even a fidget spinner!
No Useless Derivations – He focused on understanding, not memorization.
One-Liner Magic –
"Jitna mass door, utna inertia zyada."
"Torque \= Force × Distance, jaise darwaza khulta hai!"
"Jitna halka object, utna zyada angular velocity!"
For the first time, I wasn’t just listening. I was understanding.

The Final Blow: The Ultimate Question
He ended the class with a challenge.
"Agar ek patla ladka aur ek mota ladka same swing pe baithe hain, aur dono ne apne haath bandh liye, kaun zyada ghoomega?"
The class thought hard. Someone whispered, “Patla wala?”
"Haan! Kyunki uska moment of inertia kam hai. Jaise figure skaters jab spin karte hain, toh haath bandh lete hain taaki jaldi ghoom sakein!"
Mind \= Blown.

The Aftermath: A Changed Perspective
I left the class feeling something strange.
Excitement.
For the first time, I wanted to study Rotational Motion.
I went back to my hotel room, opened my book, and instead of seeing random Greek symbols, I saw bicycles, doors, and pizza slices.
And in my mind, I whispered:
"Shukriya, Anand Sir."
