Learning Paths
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.
Chapter 4
Newton's Laws of Motion, Friction, Momentum and Collisions, Circular Motion
Why does a book on a table stay still, a hockey puck slide on and on, and a car skid on a wet road? Three laws, written by Newton more than three hundred years ago, answer all of these and many more. In this chapter we learn the three laws, we draw the forces on a body, we solve problems with pulleys, slopes and friction, and we find the force that keeps a car on a bend. Python solves the equations and draws the graphs.

Chapter 2
Newton's Laws of Motion, Momentum and Collisions, Friction
Have you stood in a bus when the driver braked hard? You moved forward, and nobody pushed you. Why did that happen? In this chapter we find out. We learn what a force is and how a force changes the way things move. We also see why every push has a push back. Newton explained all of this with three laws. We discuss them one at a time, and we use Python to watch them work.
