Work and Power

Mr. Andersen explains the concepts of work and power in physics. Work is defined as applying a force over a distance, measured in joules, while power is the rate of doing work, measured in watts. The video provides examples of calculating work in different scenarios, emphasizing the importance of force and distance being in the same direction. It also covers how to measure work in a lab setting using force versus distance graphs and discusses the historical context of James Watt's contributions to understanding work and power.
