The height of a projectile thrown vertically with an initial velocity u from an initial height x₀ is given by

h(t) = -(1/2) g t² + u t + x₀

Below is shown the simulation of a projectile thrown vertically where different values of u and x₀ can be entered and the path (in red) as well as the change of h in terms of the time t are displayed.

Input values for u and x₀ and press "start/restart" button.
