This interactive animation illustrates projectile motion physics using the quadratic height equation, plotting trajectory as a D3 line path with a moving circle representing the object. Sliders allow adjustment of launch angle, initial velocity, height, and gravity, with the trajectory path and computed metrics like maximum height and range updating accordingly. The code relies on D3 scales, axes, and interval-based animation, generating synthetic data through the flight-time formula on each parameter change. A play button restarts the motion sequence.
