Chapter 4 of Class 11 Physics — Laws of Motion — is one of the most important chapters in mechanics. A solid grasp of Newton’s Laws, momentum, friction, and circular motion is essential before moving ahead in the syllabus. To help you check your preparation, I have designed a 30-mark practice test covering all key […]

What is Periodic Motion : In Physics, a motion that is regular and repeating is called Periodic Motion. The time to complete one full motion is called the Time period of the Periodic Motion
What is SHM: A Simple Harmonic Motion is a special case of Periodic motion where a physical quatity varies sinusoidally.In this Periodic motion the restoring force is directly proportional to the displacement. The object oscillates between two position and Motion is sinusoidally in nature.

A non inertial Frame of Refrence is the frame of refrence which is having acceleration a. Example Free Falling elevator
Newtons law are valid in inertial frame of refrence only. We cannot apply them as it is in non inertial frame of refrence as it left out the acceleration of the object because of the frame of refrence.
Let me provide simple example to illustrate this.

We all know what happens when we turn on a torch or plug in a fan—the device starts working as soon as we flip the switch. But have you ever wondered why the current starts flowing, and how it relates to the voltage we apply? Let’s break down the relationship between current and voltage using

The resistance of an ideal voltmeter is considered to be infinite. This characteristic is crucial for the accurate measurement of voltage (potential difference) across two points in a circuit without affecting the circuit itself. Concept of Ideal Voltmeter An ideal voltmeter is a theoretical device that measures the potential difference between two points in a

Introduction In physics, equilibrium refers to a balanced state where the net force and net torque acting on a body are zero. This concept helps us understand why objects either remain at rest or move with constant velocity. When studying mechanics, we encounter two primary types of equilibrium based on the motion characteristics of objects.
