<##>Download Dynamics Momentum FBDs Graphs.pdf — Expanded crash course on momentum, impulse, force-time graphs, free-body diagrams, slope/connected-body FBDs, and graph interpretation.
<##>Quick Overview | Area | Key idea | |---|---| | Momentum | \(p = mv\), vector quantity, direction/sign matters. | | Impulse | \(J = F\Delta t = \Delta p\). Force over time changes momentum. | | Conservation | Total momentum before = total momentum after if external resultant force is negligible. | | FBDs | One diagram, one object; only forces acting on that object. | | Slopes | Resolve weight into \(mg\sin\theta\) along slope and \(mg\cos\theta\) into slope. | | Graphs | Force-time area = impulse; momentum-time gradient = force; force-displacement area = work. |
