physics notes/work energy power
Revise work, kinetic energy, potential energy, power and conservation.
Chapter Overview
Short, exam-focused cards for the full Work Energy Power chapter. No long derivations, just clean direction before you begin.
Introduction to Work, Energy and Power
Build the core language of mechanics: force transfers energy, energy measures ability to do work and power measures rate.
Work Overview
Work depends on force, displacement and angle. Positive, negative and zero work become easy once direction is clear.
Energy Overview
Kinetic and potential energy help solve motion problems without tracking every force at every instant.
Work-Energy Theorem Overview
The net work done on a body equals the change in kinetic energy. It is a powerful shortcut for variable force problems.
Conservation of Energy Overview
When only conservative forces do work, mechanical energy remains constant and many mechanics questions become simpler.
Power Overview
Power compares how fast work is done. It appears in machines, engines, lifting problems and efficiency questions.

Why Work Energy Power Is Important
Work, Energy and Power is one of the most important mechanics chapters. Concepts such as kinetic energy, potential energy, conservation of energy and power are repeatedly used in Rotational Motion, Gravitation, SHM and Modern Physics. Questions are frequently asked in CBSE, NEET, JEE Main, JEE Advanced, IB, IGCSE and A-Level examinations.
