Examples of projectile in the following topics:
- 
Scientific Applications of Quadratic Functions- The maximum height of a projectile launched directly upwards can also be calculated from a quadratic relationship.
- The same maximum height of a projectile launched directly upwards can be found using the time at the projectile's peak ($t_h$):
 
- 
Applications of the Parabola- The parabolic trajectory of projectiles was discovered experimentally in the 17th century by Galileo, who performed experiments with balls rolling on inclined planes.
