Cannon Ball Gravity Model

This example demonstrates the numerical model of a cannonball's trajectory under gravity. Key math concepts include calculus, vectors, parametric equations, and coordinate geometry. The construction uses GeoGebra's Iteration command to simulate the motion, involving objects like Cannon, vx0, vy0, xacc, yacc, n, vx, vy, xpos, ypos, Ball, and button1. Suitable for high school and above students to understand the integration of physics and mathematical modeling.
