Kinematics from scratch

One map: from s = v·t through a and throws to energy. Each node has one short note and a next link.

Start with part 1 of the series: uniform motion. Full table of contents: Physics without mysteries.

How it works

Kinematics describes motion without asking where the force comes from. First the constant-v model (s = v·t), then constant a (SUVAT), then gravity in falls and throws, then the incline and a bridge to F = ma and energy.

On Calcboxer intents stay split on purpose: the v–s–t solver is not the same as “distance only”, and trip average speed is not instantaneous speed. Vertical / horizontal / angled throws have separate pages because learners search them separately.

If you are starting from zero, follow Physics without mysteries — eight articles with a worked problem and one-click calculator fill.
