Uniform Linear Motion and Uniform Circular Motion Models

In this program, a maneuvering target undergoes three distinct phases: initial uniform linear motion, uniform circular motion, and a return to uniform linear motion. During these phases, the target is subjected to various physical mechanical influences that affect its trajectory. In the initial uniform linear motion phase, the target maintains constant velocity and direction, though code implementations may incorporate factors like air resistance or external disturbances that cause minor trajectory deviations through perturbation algorithms. During the uniform circular motion phase, the target experiences centripetal force (implemented through vector rotation calculations and angular velocity maintenance) that guides it along a circular path. While both speed magnitude and direction remain constant in this phase, the centripetal force implementation creates curved trajectory curvature through continuous direction adjustment algorithms. Finally, in the return to uniform linear motion phase, the target resumes straight-line movement with constant velocity and direction. Throughout the entire motion process, the linear velocity magnitude v remains unchanged (enforced via velocity normalization functions), but multiple minor trajectory adjustments may occur due to the programmed physical mechanics influences, implemented through iterative position update methods and force application routines.
