The Physics of Car Crashes
Gasoline packs enormous energy, and only a fraction of it becomes the car’s motion—yet that fraction is still enough to make crashes violently...
A Simple Proof of Conservation of Energy
A force that doesn’t explicitly depend on time automatically leads to conservation of energy: the system’s total energy stays constant even as...
Windmills Are NOT Like Dams
Windmills can’t behave like dams because wind energy comes from motion: slowing the air to extract power inevitably reduces how much wind continues...
The Trebuchet Challenge | Space Time
Energy’s conservation turns a messy trebuchet mechanics problem into a clean calculation: once the counterweight and projectile start and end at...
