A molecule in the surface has greater potential energy than a molecule inside the liquid. The extra energy in the surface layer is called the surface energy
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 different spring mass systems and determine angular frequency / time period of the simple harmonic motion (includes JEE Main & Advanced questions)
Capacitance of parallel plate capacitor with dielectric slabs in series and parallel along with dielectric slab of varying dielectric strength
Top 120 question types make up for 70 marks out of 100 in JEE Main physics. Score 99+ percentile by mastering these JEE Main important questions for physics
Consider a system of five conducting parallel plates of large area A. The charge on plates is Q, 2Q, 3Q, 4Q and 5Q. Determine the charge on different surfaces.
Here is the center of mass formula list for different shapes that you will come across in your preparation for JEE Main and JEE Advanced.
Moment of inertia of a rigid body is its resistance to change in its angular velocity. Let's explore the moment of inertia of commonly encountered simple objects
8 types of JEE Main important questions on center of mass and linear momentum that one should master to crack JEE Main. For JEE Advanced you should master all.
Here are the force and motion notes (concepts summary) which you should use to get started or for your revision as you are getting ready for JEE Main & Advanced
Given a two or three dimensional variable force vector, F, acting on the particle as it moves along a two or three dimensional path, the work done by F is...
Here are the work energy and power notes (concepts summary) which you should use to get started or for your revision as you are getting ready for JEE Main and JEE Advanced
From gravitation you can expect 1 question each in JEE Main and JEE Advanced. This topic can be scoring if you can master all different types of questions
From rotation, you can expect 1 to 2 questions in JEE Main and 1 to 2 questions in JEE Advanced & it is considered one of the more difficult topics in physics
In JEE Main you can expect up to 2 questions from center of mass while in JEE Advanced you can expect 1 question from this topic.
From work energy power you can expect 1 question in JEE Main and JEE Advanced each. Remember that this chapter is fundamental to most of the chapters to come.
Relative motion typically refers to either the relative position of one object measured from the other or the relative velocity of one with respect to another
Here are the kinematics notes (concepts summary) which you should use to get started or for your revision as you are getting ready for JEE Main and JEE Advanced
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.
Let's explore circular motion and understand types of circular motion (uniform and non-uniform circular motions) and kinematics of circular motion.
