## 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…
