using Tracker Model Builder to create theoretic graphs for simplifying Physics concepts. axes rotated 180 degree for a downward as positive displacement graph.

Note that when t = 0.5 s, y = 1.25 m 

using Tracker Model Builder to create theoretic graphs for simplifying Physics concepts. axes rotated 180 degree for a downward as positive velocity graph. notice world view has velocity uniformly increasing magnitude vectors drawn too.

Note that when t = 0.5 s, vy = 5 m/s 

using Tracker Model Builder to create theoretic graphs for simplifying Physics concepts. axes rotated 180 degree for a downward as positive acceleration graph. notice world view has acceleration vectors of equal=10 m/s^2 drawn too.

Note that when ay = 10 m/s^2
