Chapter 1 flight mechanics
The starting point is Newtonian mechanics: force, mass, acceleration, work, energy, moments, pressure, density, and vectors.

This page combines original engineering notes, formulas, navigation, backlinks, and canvas animation for aircraft and spacecraft flight mechanics.

Flight mechanics begins before aircraft shapes appear. Every later aerodynamic, propulsive, and orbital result is a force or moment balance. Engineers resolve forces into components, track acceleration from unbalanced force, and use energy and power to connect speed, height, climb, and range.
A useful habit is to draw the free body first: weight downward, lift or normal force, drag opposite motion, thrust along the propulsor axis, and any moments about the center of gravity. The same diagram discipline works for aircraft, rockets, and spacecraft.
Design reviews check unit consistency, sign convention, frame of reference, load path, and whether a simplifying assumption hides a real coupling such as fuel slosh, rotating inertia, or compressibility.
Do not treat scalar speed as the whole velocity state. Direction matters, especially in climb, turns, launch trajectory, and orbital injection.
Aircraft flight mechanics and rocket flight share the same foundation: force balance, moments, energy, mass properties, stability, compressibility, and trajectory control. The rocket pages use these principles during max-Q, staging, re-entry, landing, and orbital insertion.
