Do you know how velocity of different points behaves in rolling motion? �

This small concept from Rotational Motion can help you solve many JEE Physics questions easily.

In this JEET Series Reel, learn: � Rolling without slipping concept
� Velocity of points on a disc
� Centre of mass velocity idea
� Smart problem-solving approach
If you are preparing for JEE 2026 / 2027 or NEET, strong concepts like this make the real difference.
� Learn daily. Improve daily.

Most students try to memorize formulas in Rotational Motion…
But very few actually understand how velocity works in pure rolling.

And that is exactly why many students get confused when they see questions like:

Why velocity of top point = 2V?
Why velocity of bottom point = 0?

The difference between average students and toppers is simple:

Toppers understand the concept.
In today's JEET Series video, we break this concept in the simplest possible way so that serious JEE / NEET aspirants can build strong fundamentals.
If you are preparing for JEE 2026 / 2027, do not skip rotational motion concepts like this.

Welcome to the JEET Series by AMIITJEE CAREER INSTITUTE.

In this video, we discuss an important concept from Chemical Equilibrium — how the equilibrium constant (K) changes when the stoichiometric coefficients of a balanced chemical equation are multiplied by a number (n).

This concept is very important for solving equilibrium problems in JEE Main, JEE Advanced, and NEET.

If a balanced chemical equation is multiplied by n, then the new equilibrium constant becomes:
Understanding this rule helps students quickly solve transformation-based equilibrium questions.

In this lecture you will learn:
✔ Rules for changing equilibrium constant (K)
✔ Effect of multiplying the reaction by n
✔ How to calculate new K value
✔ Important equilibrium transformations:
Reversing reaction → K becomes 1/K
Multiplying reaction → K becomes Kⁿ
Adding reactions → K values multiply
✔ Application in JEE / NEET numerical problems
This video is part of the JEET Series, where we focus on concept clarity, logical understanding, and exam-oriented preparation.

🎯 Ideal for:
JEE 2026 aspirants
JEE 2027 aspirants
NEET 2026 aspirants
NEET 2027 aspirants

📌 Study Tip:
Always observe how the reaction is modified before calculating the new equilibrium constant.

In this video, we explain an important concept from Chemical Equilibrium — the relation between Reaction Quotient (Qc) and Equilibrium Constant (Kc). This concept helps us predict the direction of a chemical reaction and is frequently asked in JEE and NEET examinations.
By comparing Qc and Kc, we can determine whether a reaction will proceed in the forward direction, backward direction, or is already at equilibrium.
In this lecture you will learn:
✔ What is Reaction Quotient (Qc)
✔ What is Equilibrium Constant (Kc)
✔ Relation between Qc and Kc
✔ Application of this concept in JEE / NEET numerical problems
