    Orbital simulation - Calculate object position over time in a 2d plane

    Hi Im busy creating an application to simulation a rocket in orbit. I am having trouble as the results I am getting are incorrect. Could someone please check if I am using the correct method as stated below. Everything works on a 2d plane, and has a x and y coordinate and a x and y...

    Rocket engine gimballing - torque and angular acceleration question

    sjb27 and Bandersnatch. I do really appreciate you guys taking the effort to help, alas I have run out of time and cannot afford to work on the problem any longer. My thesis is not graded on the 'correctness' of the application rather the things you learned along the way kinda thing. I want...

    Rocket engine gimballing - torque and angular acceleration question

    Hi Bandersnatch Thanks for the reply. Unfortunatley i don't have time at the moment to give an in depth reply. The solution I am using seems be working but its almost undoubtly incorrect. I will be in touch later tonight

    What Is the Correct Speed of the Moon at Perigee?

    The formula I'm using does not take into account the mass of the moon, only the mass of the earth. Am I using the wrong formula?

    What Is the Correct Speed of the Moon at Perigee?

    ok so the new values I am using G = 6.67384 × 10^-11 m3 kg-1 m = 5.97219*10^24 kg p = 363295000 m a = 384399000 m im getting a result of 1075.7984 m/s wrong? correct?

    What Is the Correct Speed of the Moon at Perigee?

    Hi Im trying to calculate the speed of the moon at perigee but i don't know where I am going wrong. As i know the formula is v = sqrt[ GM( (2/p) - (1/a) ) ] where g = gravitation constant m = mass of the earth p = distance perigee from the earth a = semi major axis The values I am using are...

    Rocket engine gimballing - torque and angular acceleration question

    Hello Firstly i just registered, I am a final year computer science student and I am busy working on my thesis (the deadline is fast approaching) I am working this application of a rocket going into orbit and physics is not my forte. I need some help on converting the gimbal of a rocket...
