The objectives of the study discipline

Understanding of basic principles describe the movements of mechanical objects. To provide the students with the theoretical basics of dynamics and dynamic modeling of technical processes and natural phenomena. Study of the basic laws of dynamics, its General theorems. The establishment of mathematical models that describe the movement points and systems under the influence of specific classes of forces. Skills of problem solving.

As a result of the study, the student should be able to:

  • describe motion of material points and solids and find their kinematic characteristics: trajectory, speed and Acceleration;
  • describe a complex movement points and solids.
  • apply basic laws and General theorems Dynamics point motion study points in field kvaziuprugih field forces of the central powers, when driving point in non-inertial systems;
  • apply the General theorem for Dynamics motion studies of mechanical systems;
  • compose and address the problem of the motion of bodies of variable mass.



Basis of mathematical analysis, differential geometry and differential equations.
