Vertical Motion Models
For an object that is thrown up or down, the Vertical Motion Model is:
h = __________________________
t = __________________________
*v = __________________________
s = __________________________
* Velocity indicates speed and direction

Up is _________________

Down is _________________
The graph of a Vertical Motion Model is a __________________________.
̶ The vertex will give you the ______________ the object gets to its maximum ________________:
̶
vertex: (x, y) → x = _____________ and y = __________________________
The x-intercept ___________________________ will give you the ________________ that it hits
the_______________:
x-intercept: (x, 0) → x = _____________ and y = 0 _____________________________
Good calculator window for vertical motion problems:
x min = -10
x max = 10
x scl = 1
y min = -30
y max = 300
Vertical Motion Model:
Our graphing calculator uses x and y instead of t and h:
Examples:
1. An object is thrown upward at 80 ft/sec from ground level.
a.) Write a vertical motion model. _________________________
b.) What is the maximum height? _________________
c.) When does it reach its maximum height? _________________
