Apparently it covers:

Dynamics of a single particle
• Vector calculus
• Newton’s 2nd law
• Work and line integrals, arclength
• Conservative systems and conservation of energy
• Central forces and conservation of angular momentum
• Planetary motion and kepler’s laws
Dynamics of many particle systems
• Systems with constraints and general coordinates
• Conservative systems, stable equilibria
• Lagrangian Mechanics and calculus of variations
• Hamiltonian mechanics
• Poissson brackets and canonical transformations

Unfortunately, what is said about angular momentum in 2.12 is inadequate, in that it implicitly assumes that the angular momentum is to be calculated with respect to the fixed origin.
This is by no means necessary, and the tutorial ought to have included the general case, in which, for example, the point we calculate the angular momentum with respect to assigned a non-zero velocity.

• Non-inertial reference frames

I find this content to be highly relevant and important in understanding the motion and behavior of particles in various systems. The topics covered, such as Newton's laws, conservation of energy and angular momentum, and Lagrangian and Hamiltonian mechanics, are fundamental principles that govern the dynamics of particles. These principles are essential in many areas of physics, including classical mechanics, celestial mechanics, and even quantum mechanics. By understanding the dynamics of a single particle, we can then apply these principles to more complex systems with multiple particles, constraints, and non-inertial reference frames. This content provides a strong foundation for further studies and research in various fields of physics and engineering. Overall, I believe this material is crucial for any scientist or engineer who wants to understand and analyze the behavior of particles in different systems.
