If an object is given an initial velocity in any direction and then allowed to travel freely under gravity only, it is called a projectile motion.
It is basically 3 types
- horizontally projectile motion
- oblique projectile motion
- included plane projectile motion
The path followed by a projectile is called its trajectory.
