Introduction
Theoretical Mechanics is a traditional subject of studying the general rules of mechanical motion
Mechanical Motion: the change of object’s dimensional position by the elapsed time
Objects : the mechanical motion of object which its speed is far less than the velocity of light.Based on the Newton and Galileo’s classic theory
Classic Mechanics 经典力学Quantum mechanics 量子力学
2、Scope of Theoretical Mechanics
Introduction
Three Parts of Theoretical Mechanics
STATICS (静力学)Body’s equilibrium rules, general property of Force and its resultant principles.
KINEMATICS (运动学)Geometrical properties of body’s motion, except the reason of motion.
DYNAMICS (动力学)Relationship between force and motion
2、 Scope of Theoretical Mechanics
Introduction
FORCE
DefinitionThe relative effect between bodies, it can change the mechanical motion status and produce deformation of a body
Two effects of Force
