Entities → interactions → mechanisms → scales → measurement
Build motion from state, interaction and invariants.
Classical mechanics is most powerful when force-based and conservation-based descriptions are treated as complementary representations of the same dynamical system.
Newtonian dynamics
Relate changes in momentum to interactions while defining frames, constraints and idealizations explicitly.
Work & energy
Use scalar energy accounting to simplify motion when force descriptions become cumbersome.
Momentum & rotation
Extend translational ideas to collisions, angular momentum, torque and rigid-body motion.
Oscillation & coupled motion
Study restoring forces, normal modes and resonance as recurring structures across mechanical systems.
Keep the boundaries visible.
These separations prevent nearby ideas from collapsing into one another before the subject is understood.
kinematics ≠ dynamics
mass ≠ weight
energy conservation ≠ energy constancy in every subsystem
Questions that organize the Side.
Use these to test whether the model is becoming explanatory rather than merely familiar.
When is a force description more informative than an energy description?
Which idealizations make a mechanical model solvable without destroying the phenomenon of interest?
How do constraints change the degrees of freedom of a system?
What should carry weight here?
Prefer measured trajectories and forces where available, with model assumptions about friction, rigidity, isolation and reference frames stated rather than hidden.
