NCERT Class 11 Physics – Work, Energy and Power
The chapter Work, Energy and Power in NCERT Class 11 Physics focuses on the concepts that explain how forces cause motion and energy transfer. Work is defined as the product of force and displacement in the direction of force, while energy represents the capacity to do work. The chapter distinguishes between kinetic energy, associated with moving objects, and potential energy, related to an object’s position.
The principle of conservation of energy is discussed, stating that total energy remains constant in an isolated system. Power, the rate of doing work, is also introduced, along with its practical applications in machines and daily life. Students learn to solve numerical problems on work, energy, and power using formulas and vectors. By practicing NCERT examples and exercises, learners strengthen analytical skills and build a solid foundation for board exams and competitive tests like JEE and NEET.
