Why does a projectile fired along the horizontal not follow a straight line path ?

Show that path of a projectile, fired horizontally, from the top of a tower is parabolic in nature.

(A): The path followed by one projectile as observed by another projectile is a straight line in uniform gravitation field. (R): The relative velocity between two projectiles at a given place doesn't change with time. Because their relative acceleration is zero.

A projectile is fired at an angle theta with the horizontal in a resistance from atmosphere. Which of the following quantities does not change during the motion ?

In the following questions a statement of assertion (A) is followed by a statement of reason ( R). A: Path of a projectile with respect of another projectile is straight line . R : Acceleration of a projectile with respect to another projectile is zero.

Why does the direction of a projectile become horizontal at the highest point of its trajectory?
