Students discover that the concept of "work" to a scientist is very different from what we think of as "work." To a scientist, work is accomplished when an object with resistance is moved a distance. To a scientist, reading an assignment in a textbook represents no work at all! Potential and kinetic energy and friction are also discussed.
