Energy is never lost, only transformed through motion and fields

In short: What does it actually mean to 'have' energy? This video explores the fundamental physics of energy, moving past common misconceptions to define its core characteristics and how it manifests in our universe.

Paul Andersen breaks down the age-old question of what energy is by focusing on its most defining trait: conservation. While energy appears in diverse forms, it remains constant over time rather than being created or destroyed.

To categorize these forms, the video explains that all energy falls into three primary categories: functions of motion, positions within a field, or radiation. The content also provides a structured K-12 teaching progression for educators looking to explain these complex concepts to students.
