Projectile motion: When an object is thrown obliquely near the earth surface,it moves along curved path,this motion is called projectile motion.Here in this motion, is also an example of projectile motion with angle of inclination being 0° with the horizontal.Time of flight is the total time taken by an object to travel in air before coming to the ground.Since the ball is shot horitantally, therefore vertical component of velocity is zero.Accleration in horizontal axis is also zero.
