How does the vertical component of a pro- jectile’s motion compare with the motion of vertical free fall when air resistance is negligi- ble?

Explanation:

In case of projectile motion, the acceleration acts is in vertical direction only which is due to the acceleration due to gravity.

In case of free fall the body moves along the vertical straight line, which is again under the acceleration due to gravity. Thus the motion of a body under free fall and the vertical  motion of a projectile is same.
