About this document
Class 11 Work, Energy & Power Formulas by Paul George is a document available to read on EtoBox.
1. Work is defined as the product of force and displacement in the direction of the force. Work done by a force is zero if its displacement is zero. 2. Kinetic energy is the energy possessed by a body in motion. It is defined as half mass times velocity squared. 3. Potential energy is the energy possessed by a body by virtue of its position or configuration. Gravitational potential energy and elastic potential energy are conservative forces while friction forces are non-conservative.
