What makes a clock tick or a bulb light up? The concept of work is explained to a backdrop of clever animation. Physics fans learn that the amount of work equals the product of the force and distance, and that the rate equals the amount of energy transferred over time. Sample equations are solved to determine Joules per second required for both the clock and the bulb. This makes a strong introduction to the concept of work. Follow it up by working some practice problems with your class.
