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.
Which formula when
| Node | About | Where next |
|---|---|---|
| Uniform motion | Constant v; solve any two of v, s, t. | Article 1 + uniform-motion calculator |
| Distance s = v·t | Distance only from known v and t. | uniform-motion-distance |
| Average speed | v = s/t for the whole trip (stops included). | average-speed |
| Acceleration | Just a = Δv/t before distance enters. | acceleration |
| Falls / throws | g = const; vertical, horizontal, angled. | Throw hub + articles 4–6 |
| Incline | a = g sin α (no friction) and μ variant. | Article 7 + incline-no-friction |
| Force F = m·a | Where a comes from — Newton II. | force-f-ma |
| Ek / Ep | ½mv² and mgh — energy in motion. | Article 8 + energy calcs |
