Most artillery games are based on the **Projectile Motion Formula** used to trace the trajectory of a projectile thrown in the air. Due to gravity, its trajectory will be a **parabola** which shape will vary based on the **angle** and **initial velocity** of the projectile.

Use the script below and see what happens when you change the angle. (e.g. use a value between 0 and 90 degrees) or the velocity.

These pages helped us with defining the equation for the trajectory of the projectile:

Angry Birds, Tanks, Worms, Sports/Ball based games (Basketball…) all use a similar algorithm and formula. Can you think of any other video games based on this formula?
