Thus, Lesson 1 of this unit will focus on the definitions and meanings of such terms as work, mechanical energy, potential energy, kinetic energy, and power. When a force acts upon an object to cause a displacement of the object, it is said that work was done upon the object.
In physics, we define energy as the ability of something to do work. Energy can exist in many forms. All forms of energy are either kinetic or potential. In this article, let us understand what energy is and the different types of energy in detail. Table of Contents: What Is Energy? Different Types of Energy. Kinetic Energy. Potential Energy.
Work, Energy and Power are fundamental concepts of Physics. Work is said to be done when a force (push or pull) applied to an object causes a displacement of the object. We define the capacity to do the work as energy. Power is the work done per unit of time.

Describe and calculate work and power. Section Key Terms. The Work–Energy Theorem. In physics, the term work has a very specific definition. Work is application of force, f f, to move an object over a distance, d, in the direction that the force is applied. Work, W, is described by the equation. W = fd. W = f d.
Energy is the ability for an object to perform work on another object. At its core, this is a simple definition; however, it can manifest itself in many ways. Mechanical energy. Mechanical energy is the energy possessed by an object because of its movement or position.
