Friction,t surfaces; however, there are other contributory factors. If two surfaces are described in problems as being smooth then it is implied that friction forces do not exist or that they can be disregarded.

Centres of Gravity and of Mass: Centroids,ady used the result that the ravitational forces on the individual particles of a rigid body reduce to a single force acting at some well-defined point in the body; if the location of this pointis known in a particular case the analysis is obviously greatly simplified.

Kinematics of Rigid Bodies,since engineering interest centres on particle systems of this particular kind. We first discuss the kinematics of rigid bodies, recalling that a rigid body is, by definition, a particle system for which the configuration of the particles is unchanging.

Heparin-Binding Property of Human Protein C possibility of constant speed in a straight line, since we did not have at our disposal the necessary criteria for establishing the nature of motion in general. However, if the system is not in equilibrium, then motion of some kind is certainly taking place and the study of that motion becomes all-important.

Emmanuel J. Favaloro,Leonardo Pasalicltant force requiredto bring about some specified motion. A review of the problems of the previous chapter will show that if the resultant force and its variation were known, then the complete solution for both velocity and position involved two successive integrations of the expression for the acceleration.
