Uniform Rectilinear Motion with Vector Form and Riemann Sums

This GeoGebra example demonstrates uniform rectilinear motion via an interactive animation: a body moves along a line with constant velocity, so the velocity vector is fixed while the position updates linearly with time. It also builds discrete approximations of accumulated change using time steps, connecting the idea of Riemann sums (upper/lower sums) to the notion of approaching a continuous value through finer partitioning. Key concepts include 2D vectors (representing velocity/translated displacement), arithmetic over time increments, and limit-oriented thinking through Riemann sum construction; the setup can be extended toward probability/random-process viewpoints and expected-value style readings. Construction is driven by the provided GeoGebra commands/objects: anima and animation control the playback; reinicia and start with parameters t0, t1, dt, and t (plus tt) manage the discrete time stepping; objects like M, P, v, vel generate the evolving quantities (e.g., position points and the velocity vector); texto1/texto2 annotate results; para together with tPause/tPauseAux provides pauses for observation during the animation. Suitable for middle/high school learning and for early calculus topics such as limits and numerical integration intuition.
