Dynamics is the study of bodies in motion. There are two major topics in the study of dynamics: kinematics is the study of the motion of particles and bodies, and kinetics is the study of the forces and moments required to induce motion. The motion of particles can be categorized as rectilinear and curvilinear. These types of motion also apply to rigid bodies. The motion of rigid bodies also can be described by angular motion. Energy methods are important tools for solving kinetics problems that would be cumbersome to solve by the application of Newton’s Laws. These techniques use the concepts of conservation of energy (energy can neither be created nor destroyed) and the definition of work (energy is the capability to do work). Newton’s Second Law describes the relationship between the forces acting on a particle or body and how it will accelerate.
