Mechanics: Scope and Branches

In this section: 1 table
  • Mechanics is the branch of physics that studies the motion and equilibrium of bodies and the forces acting on them.
  • Statics deals with bodies in equilibrium.
  • Kinematics describes motion without analysing its causes.
  • Dynamics relates motion to forces and mass.
  • Classical mechanics is highly accurate for ordinary macroscopic objects moving much slower than light.
BranchMain concern
StaticsBodies in equilibrium
KinematicsPosition, displacement, velocity and acceleration
DynamicsForces and their effects on motion
