PS3B – Conservation of Energy and Energy Transfer

PS3B - Conservation of Energy and Energy Transfer

Paul Andersen explains how energy is conserved within a system. In both macroscopic and microscopic collisions the amount of energy before the collision is equal to the amount after. He then defines heat as energy transfer between objects with different temperatures. He explains how heat is transferred via conduction, convection and radiation. A teaching progression K-12 is also included.
