.Rigid body - Answera body which does not deform; effects of deformation is not
considered in the analysis

.External Forces - AnswerForces responsible for the external behavior of the rigid body;
either cause the body to move or ensure that it remains at rest

.Internal Forces - AnswerForces which hold together the particles that form the rigid
body

.Translation - AnswerIs a motion in which each straight line keeps its original orientation

.Rotation - AnswerIs the motion pivoting about a point

.Principle of Transmissibility - Answerthe same line of action

.Sliding Vectors - AnswerAre forces allowed to slide along their line action
