Physics without mysteries
Eight parts from s = v·t to energy balance. Read in order or jump to the throw you have on the test.
Topic map: kinematics from scratch. Throw comparison: projectile hub.
How it works
Physics without mysteries is a school path through kinematics and simple F = ma / energy. No marketing fog — concrete formulas, when to pick which one, and a problem that fills a calculator in one click.
Order is deliberate: constant v, then constant a and braking, then gravity in throws, the incline, and finally Ek/Ep/work. You can read selectively, but parts 1–3 build the language that returns in throws.
Each article ends with Related links to Calcboxer calculators — the same pages exist in English under the EN slugs.
Which formula when
| # | Part | Slug | Topic |
|---|---|---|---|
| 1 | Uniform motion | uniform-motion | s = v·t, v/s/t solver |
| 2 | Accelerated motion | accelerated-motion | v₀, a, t → s, vₖ |
| 3 | Braking | braking | deceleration, distance, momentum, work |
| 4 | Vertical throw | vertical-throw-guide | H_max, Ep, Ek, free fall |
| 5 | Horizontal throw | horizontal-throw-guide | from height h |
| 6 | Projectile motion | projectile-motion-guide | Z, H_max, full path |
| 7 | Inclined plane | inclined-plane-guide | a = g sin α, friction |
| 8 | Energy in motion | energy-in-motion | Ek, Ep, work |
