Lever + Free Fall = Kinetic Energy
The creation (discovery?) of kinetic energy was a major step toward the creation of energy itself. It’s a pretty straight-forward concept: K.E. = ½ mv2 But how kinetic energy arrived wasn’t so straight-forward. The lever: weight x change in vertical height In their study of the lever, the Ancient Greeks identified the importance of the… Continue reading

The arguable culmination of these efforts occurred in 1604 when he discovered… Continue reading

About Me
Hi! I’m Bob Hanlon. After earning my Sc.D. in chemical engineering from the Massachusetts Institute of Technology and enjoying a long career in both industry and academia, I’ve returned to school, my own self-guided school, seeking to better understand the world of thermodynamics. Please join me on my journey.
