In uniform gravitational field without air resistance.
Vertical motion of an object falling a small distance close to the surface of a planet. It is a good approximation in air as long as the force of gravity on the object is much greater than the force of air resistance, or equivalently the object's velocity is always much less than the terminal velocity.

y(t) = (-1/2)*g*t^2+v0*t+y0
y(t) : altitude with respect to time (m)
g : gravity acceleration (9.81 m/s^2 near the surface of the earth)
t : elapse time (s)
v0 : initial velocity (m/s)
y0 : initial altitude (m)
