• h = -16t² + h₀ (in feet) or
• h = -4.9t² + h₀ in (meters)

• h = -16t² + v_ot + h₀ (in feet) or
• h = -4.9t² +v_ot + h₀ (in meters)

h = the height of the object at any given point in time
t = time the object is in motion (in seconds)
h₀ = the initial height (in feet or meters) from which the ball was dropped or launched
v₀ = the initial velocity (in ft/sec or m/sec) of the object when it was launched.
 If v₀ < 0, the object was propelled downward
    v₀ = 0, the ball was dropped from rest with no initial velocity
    v₀ > 0, the ball was propelled upward.
