Energy Forms and Transformations

The video, led by Sue from the Ohio Energy Project, explores various forms of energy and their transformations. It covers radiant, chemical, mechanical, electrical, thermal, and nuclear energy, providing examples for each. The law of conservation of energy is explained, emphasizing that energy cannot be created or destroyed, only transformed. The video includes practical examples using a no battery flashlight, solar toys, and a battery-powered car to illustrate energy transformations.
