Kinematics

Overview

**Kinematics**is the branch of classical mechanics

Classical mechanics

In physics, classical mechanics is one of the two major sub-fields of mechanics, which is concerned with the set of physical laws describing the motion of bodies under the action of a system of forces...

that describes the motion

Motion (physics)

In physics, motion is a change in position of an object with respect to time. Change in action is the result of an unbalanced force. Motion is typically described in terms of velocity, acceleration, displacement and time . An object's velocity cannot change unless it is acted upon by a force, as...

of bodies (objects) and systems (groups of objects) without consideration of the forces that cause the motion.

*Kinematics*is not to be confused with another branch of classical mechanics: analytical dynamics

Analytical dynamics

In classical mechanics, analytical dynamics, or more briefly dynamics, is concerned about the relationship between motion of bodies and its causes, namely the forces acting on the bodies and the properties of the bodies...

(the study of the relationship between the motion of objects and its causes), sometimes subdivided into

*kinetics*

(the study of the relation between external forces and motion) and

Kinetics (physics)

In physics and engineering, kinetics is a term for the branch of classical mechanics that is concerned with the relationship between the motion of bodies and its causes, namely forces and torques...

*statics*

(the study of the relations in a system at equilibrium).

Statics

Statics is the branch of mechanics concerned with the analysis of loads on physical systems in static equilibrium, that is, in a state where the relative positions of subsystems do not vary over time, or where components and structures are at a constant velocity...
