Work-Energy Theorem
Introduction The work-energy theorem is a fundamental principle in physics. It states that the work done on an object is equal to the change in its kinetic energy. This theorem is a direct consequence of Newton’s second law of motion. The Work-Energy Theorem Equation The work-energy theorem can be mathematically stated as: where: The kinetic…

Chapter 14: Work
14.1 Introduction to Work Work describes the transfer of energy to or from an object when a force is applied over a distance. It is a scalar quantity (not a vector) and is measured in units of joules (J). Understanding the concept of work and its relationship to energy is crucial for analyzing various physical…
