Perhaps you haven’t noticed, but I’ve been trying to make a bunch of physics videos. Oh, sure—I already have a ton of stuff on youtube, but it’s not linear. For my old stuff, I will solve a problem on work-energy and then do electric field stuff and then go back to kinematics. It was just whatever topic came up in class or online or whatever.

I figured I should start over and do a whole physics course—well, not EVERYTHING. No, I would do just enough to get you through the course. I hope you get the title now. Also, this is the title of that self published ebook I wrote a long time ago—since it really is the video version (but updated).

So, where am I now? I’ve got 4 chapters completed. I think it’s a pretty good start. Here are the chapters (as playlists) along with descriptions.

**Chapter 1: Kinematics**

Notice that I started off by making a title screen and all that cool stuff. I will end up dropping this so that I can make videos faster. Also, in my previous videos I was in front of a whiteboard. In this case, I’m writing on paper. Still not sure which way is better.

In this chapter:

- Introduction.
- Constant velocity in 1D.
- Example of constant velocity.
- Introduction to numerical calculations (1D constant velocity).
- Constant acceleration in 1D.
- Numerical calculations with constant acceleration (in 1D).
- Solving the “cop chasing a speeder” problem.

**Chapter 2: Forces** **and Motion**

It’s tough to start in physics with forces. There are so many things to cover. This is a shorter chapter that looks at the fundamental ideas of force and motion.

- Introduction to forces and motion. I really like this first video. It’s a conceptual look at the forces, the momentum principle and “Newton’s 2nd Law”. Guest appearances by Galileo, Aristotle, Newton.
- Forces in 1D – falling objects.
- Modeling the motion of a mass on a spring (and finding the model of a spring force). This one is long (but pretty nice).

**Chapter 3: Vectors—2D and 3D Stuff.**

The goal here is to expand kinematics into using vectors—but then you need to know about vectors.

- Intro to vectors.
- Kinematic equations with vectors.
- Example of constant velocity and position update formula in 3D.
- Intro to projectile motion.
- Finding the range for projectile motion.
- Numerical calculations for projectile motion.
- Acceleration of a block on an inclined frictionless plane. This is an example of forces in 3D.
- The physics of flying R2-D2. Using forces and air resistance.

**Chapter 4: Calculated Forces**

There are really two kinds of forces. There are forces that have an equation to determine the vector value (these are calculated forces). Then there are forces that don’t have an explicit equation (forces of constraint). This chapter just focuses on calculated forces.

- Universal gravity.
- Example of gravity—calculating the net force on the Apollo 13 spacecraft.
- Introduction to visual objects in VPython. This is a setup for the next video.
- Modeling the motion of an object near the Earth.
- Modeling the Earth-moon system.
- Mass on a spring (again) – but this time with visuals AND 3D motion.
