Centrifugal & Centripetal Forces
A centrifugal (fictitious) force is a force that ‘appears’ to act on a mass when it’s motion is described using an accelerating (rotating) frame of reference.
Here we deep dive into individual chapters of class 11th and 12th physics. We will look at the key concepts of each chapter, different types of questions asked in JEE Main and Advanced, important questions from JEE Mains and JEE Advanced perspective, and what you can do to champion that topic.
(Remember, clarity of concepts and lots of (SMART) practice is the key to success)

Let's explore circular motion and understand types of circular motion (uniform and non-uniform circular motions) and kinematics of circular motion.
Pulley problems for IIT JEE and JEE Main - Excellent way to practice free body diagrams and master application of newtons second law of motion.
Relative projectile motion - How would you determine relative position & velocity? Note, the acceleration of a projectile relative to another projectile is zero
Here we will explore the projectile motion examples that we encounter in real life from cricket to golf to basketball to volleyball.
Now let's explore projectile motion on inclined plane. Here we would establish the time of flight and range along the inclined plane
Physics NLM problems (practice problems) for JEE Main and JEE Advanced along with video of instructor (Vikas Sir) led class room discussion on how to solve them
Velocity of a projectile at any instant of time, in the vector form, is given by u cos theta i + (u sin theta - gt} j. But what will the velocity at height 'h'.
Radius of trajectory of a projectile at a point along it's trajectory is the radius of circular arc which best approximates the curve at that point and tells us how the trajectory of the projectile is curving at that point.
The trajectory of a projectile is nothing but the equation of the parabolic path travelled by the projectile, y = tan theta x - (g/{2u^2 cos^2 theta) x^2
Maximum height of a projectile is given by H = u^2 sin^2 theta / 2g. And the horizontal range and maximum height of a projectile are equal when \tan \theta = 4
Maximum horizontal distance travelled by a projectile is called it's range. It is maximum for angle of projection of 45 degrees
Two types of projectile motion are: vertical projectile motion and oblique projectile motion also known as angular projectile motion
Kinematics, study of motion, is fundamental to other chapters in physics. & you can expect 1 question in IIT JEE & 1-2 questions in JEE Main physics kinematics
Different types of questions that are asked on vectors in JEE Main physics (kinematics). The most commonly asked question in JEE Main is the angle between two vectors
For JEE Main, there are essentially 12 important questions of kinematics (Class 11) that one should be good at in kinematics. Top 3 of these question types are 1) Given constant acceleration vector in 2D/3D determine velocity or position at time t 2) Find angle between 2 vectors 3) Simple 1D Motion application with constant acceleration
Different types of kinematics questions that are asked on '1-Dimensional Motion' with particle either under a) variable acceleration & b) constant acceleration
