## Hooke’s Law, Modulus of Elasticity, Stress-strain curve Class 11

Here we will learn the modulus of Elasticity, stress Strain Curve, and Hooke’s law of Elasticity. We know that when any force causes deformation to a body the body tries to regain its original configuration. The body which fully regains…

## Elasticity | Core idea, definition, Stress and Strain class 11

Here, we will learn the concept of Elasticity, the Reason for Elasticity. We will go in a basic meaningful manner to know about interatomic forces etc. Material and its structure Every material is made up of molecules which are in…

## Power | Need, derivation, Mechanical Advantage class -11

Do we know that how work is defined for a force whether it’s a constant force or variable force, here we will discuss what is power? What’s need to define Power in Physics? What’s the expression of power for a…

## Mechanical Energy | conservation of Mechanical energy – derivation Class 11

Here we will know what is mechanical energy of a system under study , when we can conserve the mechanical energy of system ? We will derive it. Mechanical Energy Introduction to mechanical energy In classical mechanics , we deal…

## Conservative and non conservative forces and Potential energy Class 11

Conservative and non conservative forces In this article, we will discuss conservative and non conservative forces and think about potential energy and its definition,  and we will learn about What are Conservative and Non conservative forces conservative field theory. so…

## Spring Force, work done by spring force Class 11

SPRING FORCE Today we’re going to discuss the springs (not about the season) used in mechanical things, spring force, ideal springs, springs as shock absorbers, and work done by spring force. We all must have seen springs used in toys…

## Work done class 11 : basic meaning, affecting factors, & its unit

Introduction In our daily life we use the word “work done” when we do something like we push a car for some distance , we pull our bag or luggage  ,we lift something from ground floor to upper floors and…
