Work, Energy and Power
The Work and Energy Gallery features photos of windmills, cooling towers, horse drawn plows, tractors, bulldozers, wrecking balls, playground swings, ski towers, roller coasters, bunjee jumpers, pole vaulters, and more. Photos illustrate the concepts associated with work, energy and energy transformations. This gallery provides a brief and illustrative overview of the chapter and coordinates with Lessons 1 and 2 of the Work, Energy and Power chapter of The Physics Classroom Tutorial.
The Roller Coaster Physics Gallery features photos of historical roller coasters and various parts of a modern day roller coaster ride. Besides telling the story of the history of roller coasters, the photos illustrate the physics concepts associated with a roller coaster experience. Some parts of this gallery coordinate with Lesson and 2 of the Work, Energy and Power chapter of The Physics Classroom Tutorial.

Lesson 1: Basic Terminology and Concepts
Lesson 1 discusses the concepts of work, power, kinetic energy, potential energy and mechanical energy. Items in the group's pool include athletes (baseball pitchers, pole vaulters, high jumpers, platform divers, BASE jumpers, bunjee jumpers), construction site equipment, wrecking balls, meteor craters, roller coaster rides, trampolines, springs, and much more. Photos complement many of the discussions from Lesson 1 of the Work, Energy and Power chapter of The Physics Classroom Tutorial.
Lesson 2: The Work and Energy Relationship
Lesson 2 discusses the manner in which energy is transformed from kinetic energy to potential energy (and vice versa) and from non-mechanical forms into mechanical forms (and vice versa). Items in the group's pool include roller coaster rides, athletes (bunjee jumpers, pole vaulters, high jumpers, platform divers, ski jumpers), playground swings, meteor craters, and much more. Photos complement many of the discussions from Lesson 2 of the Work, Energy and Power chapter of The Physics Classroom Tutorial.
