Theorem on the addition of acceleration for a laptop and a portable reciprocating rotary motion, Coriolis acceleration and its calculation. Dynamics Dynamics is the section theoretical mechanics, which studies the mechanical motion of material bodies, depending on the reasons causing them. In statics studied the problem of reducing systems of forces to the simplest form and the relative equilibrium material bodies in the kinematics, the problem of the geometric characteristics of the mechanical motion. In the dynamics – the main section of the course – on the basis of information from the statics and kinematics and dynamics of special laws solved the problem of the relationship of forces and movements. Any mechanical movement of material bodies occurs over time in space. There is no movement of material bodies outside the area, as there is no movement inside and outside of time. Time and space can not exist apart from and independent of the motion of material bodies. Thus, they are forms of existence of matter in motion. Material point is called the material body, the rotational movements which in comparison with the translational, can be neglected. Thus does not necessarily mean a material point of the body is very small. Rigid body moving steadily, is regarded as material point. The material point is a point which is under communication, restricting its movement. Laws describe the dynamics of mechanical motion of material bodies in relation to the so-called "fixed" or "Absolute" coordinate axes relative to the axes, which are moving steadily and uniformly with respect to the fixed (inertial axis).
