A force changes motion, it does not sustain it

Leave something alone and it keeps going forever. Things on Earth slow down because friction and drag are forces you were not counting.

Drag nodes and connect the flow to understand the concept

Energy, Forces and What They Really Do

Four parts correcting the two biggest misunderstandings in basic physics. First find out where energy is actually held, then follow it to the place all energy ends up. Then discover that a force changes motion rather than sustaining it, and finish by watching forces come into balance while something is still falling at 190 kilometres per hour.

What Makes a Circuit Work

Three parts covering everything a simple circuit actually needs, in the order the ideas depend on each other. Start with the loop, because nothing works until the path closes and comes back. Then find out what that loop has to be made of, using the one test that decides every material — including the surprise that pure water insulates. Finish with the battery, which turns out to hold chemicals rather than electricity, and to be finished rather than empty when it dies.
