CONCEPT OF PROJECTILE.
Projectile refers to the motion of a body which travels freely in space but under the influence of gravity and air resistance. When a ball in kicked into air, it will travel through space in a plane. The motion in a plane is a combination of upward and horizontal motion.
The path through which a projectile travel is called trajectory.
Example of projectile
In sport,
- Throwing of discus
