Lesson 1 (from Part 1, The Mechanics of Movement)
Part 1, The Mechanics of Movement
The principle behind the action of any machine is the conservation of energy. The simple machines introduced in Part One are governed by a law of physics which states that work is composed of the effort you put in and the distance over which the effort is done. The objective of this lesson is to explore the law of the conservation of energy and a law of physics which states that work is composed of the effort you put in and the distance over which the effort is done.
1) Homework: Research the law of conservation of energy and write a brief informative essay about what it is and who discovered the law. Give several examples of how the law works.
2) Class Discussion: What is a driving force? What are ways in which the conservation of energy is relevant to the...
