Energy is defined as the capacity to do work and comes in different forms: Gravitational potential energy - this is dependent on the object’s position in a gravitational field and its mass. It increases as an object’s height above the ground increases.
The Basics of Work, Energy, and Power Objectives: 1. To describe the conditions under which positive and negative work are done and to use the work equation to calculate the amount of work done. 2. To define potential energy, to identify the two forms and the variables that affect the
A body that has energy may transfer some, or all, of its energy to another body. The total amount of energy remains constant (conserved) even if it has been transformed to another type. The amount of energy transformed (∆E) is called work W. The body losing energy does work, the body gaining energy has work done on it.

6.1 INTRODUCTION. The terms ‘work’, ‘energy’ and ‘power’ are frequently used in everyday language. A farmer ploughing the field, a construction worker carrying bricks, a student studying for a competitive examination, an artist painting a beautiful landscape, all are said to be working.
WORK ENERGY AND POWER. Definition: work is the product of the displacement and the component of the force applied parallel to the motion of the object. W = F Δx Cos θ. W = work measured in joule(J) F= force parallel to direction of motion in Newton. Δx = displacement in meters( only magnitude)
Work, Energy, and Power. “Energy cannot be created or destroyed: it can only be changed from one form to another.” —Albert Einstein. Kinematics and dynamics are about change. Simple observations of our environment show us that change is occurring all around us. But what is needed to make an object change, and where did that change go to?
