# Category Physics Class – 11

## 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…

## 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…

## Spring potential energy | definition, meaning and its derivation We that know how potential energy is defined for any conservative forces, here we will derive the Potential energy of spring. All the results are derived assuming ideal springs. The potential energy of Spring Meaning of potential energy of spring…

## Derivation of work energy theorem class 11 | 2 cases rotational and translational Work-Energy Theorem Today, we are going to derive the work-energy theorem and its derivation is universally applicable for all constant and variable forces and for translation and rotational work. Work-Energy Theorem For translation work Work Energy theorem in some books…

## Frame of reference and pseudo force | definition, meaning, concepts, formula. The frame of reference and pseudo force In Physics what we do is observe Nature, different Phenomenon and describe our observations, i.e where the event happened when the event happened and this all depends on different observers. For example: suppose…

## 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…

## Work done : basic meaning, Class 11 core concepts, work done by force, unit, factors affecting work done 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…
