We now begin the study of dynamics, the part of mechanics that deals with the analysis of bodies in motion. While the study of statics goes back to the time of the Greek philosophers, the first significant contribution to dynamics was made by Galileo (1564–1642). Galileo’s experiments on uniformly accelerated bodies led Newton (1642–1727) to formulate his fundamental laws of motion. Dynamics includes: 1. Kinematics, which is the study of the geometry of motion. Kinematics is used to relate displacement, velocity, acceleration, and time, without reference to the cause of the motion. 2. Kinetics, which is the study of the relation existing between the forces acting on a body, the mass of the body, and the motion of the body. Kinetics is used to predict the motion caused by given forces or to determine the forces required to produce a given motion. Chapters 11 to 14 are devoted to the dynamics of particles; in Chap. 11 the kinematics of particles will be considered. The use of the word
