The single insight that unlocks every projectile question: horizontal and vertical motion are completely independent. Horizontally nothing accelerates the object; vertically gravity does. Solve them as two separate problems joined only by time. This is the real knowscape from knowhere, not a picture of one. Drag it. Watch what actually changes.
A projectile is two motions wearing one path: a constant horizontal glide and a vertical fall, deaf to each other. Gravity only ever touches the vertical. Split every problem into those two stories, solve each with the equations you already own, and the parabola stops being a curve and becomes two straight-line problems stapled together.
Horizontal and vertical motions are independent—horizontal velocity stays constant while vertical motion undergoes constant downward acceleration due to gravity.
knowhere maps every concept to what it rests on and what rests on it — 1 underneath this one, 1 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.
