Motion

A bus starts to move, a ball falls, the minute hand goes round a clock. Everything moves, and a few simple ideas are enough to describe all of it: how far, how fast, and how quickly the speed changes. In this chapter you learn these ideas and read them from graphs. You use them to work out where something will be, and when. You also write a little Python and watch the numbers turn into pictures.

Describing Motion

You sit in a moving train. Are you moving, or are you resting? It depends on who is asking. In this course we learn to say exactly where something is, how far it has gone and how fast. We practise on walks, runs and bus rides.

Acceleration and Motion Graphs

A bus leaves a stop and a cyclist brakes. Their speed changes all the time. Acceleration is the number that tells us how quickly the speed changes. Then we draw the motion on a graph, and we learn to read the graph like a map.

Equations of Motion

When the acceleration is steady, three short equations answer almost every question about motion. How fast? How far? How long? We use them on braking trains and falling stones. Then we look at motion in a circle, and we check everything with a few lines of Python.
