Why Is the Displacement Graph Parabolic in a Ticker Tape Experiment?

[Missy81590]

Hi all,

I just had to do an experiment with ticker tape. Its a very common experiment dealing with displacement, velocity and acceleration. I have to graph each verse time. I figured out displacement would be a parabolic graph, but i don't understand why. Can someone please explain that for me? Thank you!

also, why would velocity graph be linear?

What does a parabolic displacement graph tell you? Think what are on your horizontal and vertical axis and think about the object moving in that manner.
