The body is a system of levers, and stacking body segments in sequence builds speed. Summation of momentum — big muscles first, small ones last — is how a bowler or thrower generates maximum velocity. This is the real knowscape from knowhere, not a picture of one. Drag it. Watch what actually changes.
Your skeleton is a set of levers, and sport is mostly the art of picking the right one and using it well.
Force summation maximizes velocity by sequentially activating body segments from large stable proximal muscles to small fast distal muscles, transferring momentum through the kinetic chain.
knowhere maps every concept to what it rests on and what rests on it — 2 underneath this one, 0 built on top. Each one says why, in a sentence, not as an arrow on a diagram.
Each one is its own knowscape in the app — built for how a particular student takes things in, not one explanation handed to everybody.
Every HSC and VCE concept in knowhere is built like this one — mapped to your curriculum, never capped by it. Free for a week. No card tricks, no lecture.
Free for a week, then $49 once — the 2026 exam pass ends itself after the last exam. 0 days of the pass left.
Free for a week, then a plan you can stop any time.
