Each learning path is one chapter: a guided route through a topic, one small course at a time. Pick a class to see its chapters in order.
A cricket ball flies in a curve, a boat crosses a river and lands far down the bank, and a stone on a string goes round and round. None of these moves in a straight line, so we need a new tool: the vector. In this chapter we learn to add vectors and to split them into parts, we describe motion in a plane with them, and we study two important cases, the flight of a projectile and uniform circular motion. Python draws the paths and does the calculations.
