1. The subject of theoretical mechanics ——————————————————————— Theoretical Mechanics——The study of the general laws of mechanical motion of objects. The position of an object in space varies over time. Including: motionless, movement, rotation, vibration, deformation, flow, wave, diffusion, and so on
2. Research content of theoretical mechanicsTheoretical mechanics deals with the motion ofmacroscopic objects moving at speeds far lessthan the speed of light. It belongs to the categoryof classical mechanics.Including:1. StaticThe eguilibrium law of an object underMechanics:the action of a force is studied.2. kinematic:Study the description of motion.3. dynamics:Study the relationship between forceand the of change motion
