Greetings! I'm encouraged by the amount of people I see viewing this website... I'm in serious need of equation help. I'm currently taking an online physics class because of my very full workload of 5 jobs, one being full time, another being very close to that, and the rest part time. (a few hours a week each - don't panic!) I'm currently about 2.5 weeks ahead in my homework! (Yay!!!) Ahh, can you tell I'm a workaholic? I've come to a real issue, and I need someone out there to maybe give me some helpful advice on where I can find out how to apply the correct equation to my problems. How do I find out what force of earths gravity would have on me as a percentage of mg? I'm trying to solve that question for 1 earth radius up, 2 earth radii up, and if orbiting in a shuttle around 200 mi up. I'm MORE than willing to do the math - I love to learn! - but I need to know where to start. I feel a little lost, and have nobody I can ask, since it's an online class. Thank you everyone!! I really appreciate it. Amanda Blackwood.
