Projectile AR

Projectile motion is a dynamic process and is the starting point of the learning two-dimensional movement. Static drawing is less prone to help students understand projectile motion. With augmented reality technology, this APP visualizes the process of projectile motion on mobile devices screens. This APP has functions to change the angle, initial velocity variables to display different trajectories, and supplements with coordinate axes. When operating this APP, users have better understanding of independence movements in two axes of projectile motion.

The procedure:
1. Prepare the graphic cards corresponding to this APP.
2. Start this APP. Aim the camera of mobile devices at the graphic card.
3. Project coordinate axes to explore independence movements from static graphic cards. Change variables to observe and compare trajectories at different angles, initial velocities from dynamic graphic cards.
