LinearMomentum — Extraction of linear momentum of rigid body relative to observer [mathematica]

LinearMomentum[A,B]

A: name of defined observer B: name of defined point

The function LinearMomentum returns the linear momentum of a rigid body with reference point B relative to the observer A.

The linear momentum is expressed using the symbol M for the total mass of the body.

Remember to invoke DeclareStates prior to using LinearMomentum.

Restart; DeclareObservers[A]; DeclarePoints[A,B]; DeclareTriads[a]; DefineObservers[{A,A,a}]; DefinePoints[{A,B,a,q1,q1+q2,q3}]; DeclareStates[q1,q2,q3]; LinearMomentum[A,B]
