Description

Given the path of a particle r=r(t), then the "inverse dynamical problem" is: what is the force F(t) acting on the particle? The problem posed will be illustrated using the example of a particle moving frictionless along a horizontal line and at the same time sliding on a rotating contour C. Assigned a uniformly accelerated motion or harmonic oscillations, the resulting equations are solved with Mathematica, and the shape of the contour C is determined, which gives rise to the prescribed dynamical behavior of the particle along a horizontal line. An animation is used to visualize the dynamics of the system under investigation.
