h = the
height of the object at any given
point in time
t = time the object is in motion (in seconds)
h
0 = the initial
height (in feet or meters) from which the ball was dropped or launched
v
0 = the initial
velocity (in ft/sec or m/sec) of the object when it was launched.
If v
0 < 0, the object was propelled downward
v
0 = 0, the ball was dropped from rest with no initial
velocity v
0 > 0, the ball was propelled upward.
