DERIVING EQUATIONS OF MOTION APPLICATIONS

The concepts of rigid body or particle dynamics are used in engineering when motion is involved. This can be motion of a fluid element, a controller such as a flap or landing gear mechanism, and trajectories of vehicles.

It is important that the principles of dynamics are well understood by engineers. An engineering problem can be thought of as a word problem, similar to word problems solved in mathematics. Dynamics provides the basics by which the equations of motions that govern the problem can be derived and applied.

Deriving equations of motion is very important for dynamics and many related fields, including flight dynamics, rotor dynamics, engine dynamics, aeroelasticity, and controls.
