Defining the Rate of Work: Presentation

Section role: supports the 'Defining the Rate of Work' section while the teacher formalizes the discoveries from the Logistics Lab Challenge into the mathematical formula for power. Slides: (1) Title — 'Power: The Rate of Work'; (2) Formal Definition — bullets: power as how fast work is done, connecting back to the warehouse robots from Section 2; (3) The Formula — presenting P = W/t with clear variable breakdown; (4) Unit of Measurement — introducing the Watt (W) as one Joule per second and James Watt's historical legacy; (5) Worked Example — step-by-step breakdown of a 600N student running up a 3-meter staircase in 6 seconds; (6) Misconception Check — distinguishing physical strength from the speed of using strength; (7) Visualizing Inverse Relationships — demonstrating how decreasing time while keeping work constant increases power; (8) Closing slide — 'Can an engine with low power still do the same total work as a high-power engine?' — hands control back to the teacher to set up the independent calculation practice in Section 4.
