    Yep I tried but I don't understand the programming language

    I Spacecraft Launches: Perigee & Apogee - Why Terminate?

    Yes Drakkith, that's what I meant, but which formulas do I use to calculate the radius 35,786 km (22,236 miles), by knowing that its period is 24 H.

    How do I calculate the radius of orbit from the period of orbit http://hyperphysics.phy-astr.gsu.edu/hbase/orbv3.html#ov

    I Spacecraft Launches: Perigee & Apogee - Why Terminate?

    why spacecraft launches are usually terminated at either perigee or apogee?

    I William skinner Machine gravity

    Could someone explain under which principle does Skinner's machine operate? Is it just a free falling mass that's taken back to it initial position by very little input energy, thus generating a constant gradient or potential difference, and generating energy, or is it just storing kinetic energy?

    An application of free fall (DE) model to industry

    Hi again, maybe this application is too simple. Is there any other application in which Newton's laws of motion and the gravitational force are involved? For example, my teacher told me that one application could be elevators, but I need another one.

    An application of free fall (DE) model to industry

    Could someone tell me an application of the model of free fall to industry or more generally by using Newton's second law and the law of gravitation, construct a model similar to the free fall one, that has an application in industry
