Question

A cannonball is launched from a cannon. Which of the following motion graphs for the cannonball will form a parabolic shape?

acceleration vs. time
None of the listed answers are correct
vertical position vs. horizontal position
velocity vs. time

Answer 1

By definition, a cannonball is a projectile and its path follows a parabola because of its uniform acceleration from gravity. The answer is vertical position vs. horizontal position.

Answer 2

cannonball has constant acceleration in vertical direction by gravity. so its vertical position vs horizontal position will be parabolic in shape.
