Goals

The basics of kinematics and kinetics are taught. The task of kinematics is to describe the position of systems in space and the changes in position as a function of time. This includes the movement of a point in space and the flat movement of rigid bodies. The connection between movements and forces are the subject matter of kinetics.

The aim is to present the basic laws of mechanics in the form of impulse and angular momentum and to apply them exemplarily to mass points and rigid bodies. Their inertia properties are also discussed. In addition, impact processes of a rigid body.

Topics

Unidirectional motion
Motion of a point in space

Basics of spatial motion of rigid bodies
Kinetics of rigid bodies
Fundamental laws of mechanics (law of conservation of linear and angular momentum) and laws derived from it (power and energy theorem)
Inertia of rigid bodies
Impacts
Principle of virtual displacements
Lagrange's equations
