If the machine is just launching rocks at a specified angle and velocity, then no it is not computing a parabola. The rock&#x27;s trajectory traces a parabola, but it has not been &quot;computed&quot; (in my view). A computation to me involves an explicit mathematical result related to some specific intent or question, not just physical objects playing out the laws of nature. The computer would have to make a statement, a result - &quot;based on my calculations, at time X the rock will be at position Y.&quot;
