Synopsis

This PSSC physics film shows 24,000 tons of coal unloaded from one boat, at 60 tons per minute. Demonstrates the principle of conservation of energy using a coal-fired power plant as a practical example. It details the process of converting the potential energy of coal into thermal energy and then into electrical energy. Key components of the plant, such as the boiler, turbine, and condenser, are explained, showcasing how energy flows through the system. The video emphasizes that energy is conserved throughout the process, with minimal losses, as it transitions from coal to electricity. Physics instructor Emily Cizmas adds, “The note at the end of the energy video about back pressure on the turbine is often neglected at the intro level but is so important.” Filmed at the New England Electrical Plant, Salem Massachusetts.
