What is the formula for vertical motion? Thank you.
You aren't going to get much just by looking at the equation. I'd recommend posting the question.
Here is the basic equation for freefall 1-D motion in the vertical direction.
$\displaystyle y = y_0 + v_0t - \frac{1}{2}gt^2$
where
y is the position at time t
y0 is the initial position
v0 is the initial velocity
g is the acceleration due to gravity
t is the time (assuming we start the clock when the object is at y0).
In this equation I made the assumption that +y is in the upward direction.
