Physics and chemistry for understanding space · A guided course

Energy and momentum

Balance energy, follow recoil, and understand what keeps a spacecraft pointed.

Connect work and power to motion, collisions, and spacecraft rotation. Six lessons use original worked examples and preserved mission photographs to make conservation laws practical without hiding their assumptions.
