Line 32:

likewise for Y and Z.

The former equation (gravitation) may look forbiddingforeboding, but its calculation is no problem. The latter equations (motion laws) seems simpler, but yet it cannot be calculated. Computers cannot integrate, they cannot work with infinitesimal values, so instead of dt we use Δt and bringing the resulting variable to the left:

<math>\Delta v_x = a_{x} \Delta t </math>, and: <math>\Delta x = v_{x} \Delta t </math>
