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…

Gravitational Potential Energy
Gravitational potential energy is a form of potential energy that an object possesses by virtue of its relative location within a gravitational field. When an object is lifted against the force of gravity, work is done on the object, and gravitational potential energy is stored in the object. Formula for Gravitational Potential Energy The formula…

Kinetic Energy
Kinetic energy is a type of energy that an object possesses due to its motion. When an object is in motion, it has the potential to do work, and kinetic energy is the energy associated with this potential. Formulas for Kinetic Energy The formula for translational kinetic energy is: where KE is the translational kinetic…
