What is the formula for vertical motion? Thank you.
Here is the basic equation for freefall 1-D motion in the vertical direction.
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.
