Gravitation & Orbital Mechanics: Is One Method More Correct Than the Other?

AI Thread Summary
The discussion centers on the differences between methods used to solve gravitation and orbital mechanics problems in a textbook. The original poster finds that their answers, derived from known orbital equations, differ slightly from the textbook solutions, which often utilize conservation of mechanical energy. Participants suggest providing specific problem examples and detailing the numerical methods used for better assistance. The conversation emphasizes the importance of clarity in problem-solving approaches to determine the most accurate method. Overall, the effectiveness of different methods in solving these problems is questioned.

I have been going through problems in my textbook and have a question.
The chapter is on gravitation and orbital mechanics. When answering the problems I seem to head towards different methods than what the book prescribes. My answers, primarily using known orbital equations, are close, but not quite the answers the book has in the back. Using the solution guide from Chegg, I find that they often use the conservation of mechanical energy to find answers the book more readily agrees with.
Is one way more correct than the other?
thanks​

Hi JaDi13. Welcome to PF!

It is rather difficult for us to understand what the problem is from what you have posted. If you could provide us with an example of a problem and show us your approach and the textbook solution we could probably help you.

When you provide more details as @Andrew Mason asked, please include your numerical methods. For example, numerical integration.
 

Thread '1:1 versus 2:1 Mechanical Advantage debate'

The rope is tied into the person (the load of 200 pounds) and the rope goes up from the person to a fixed pulley and back down to his hands. He hauls the rope to suspend himself in the air. What is the mechanical advantage of the system? The person will indeed only have to lift half of his body weight (roughly 100 pounds) because he now lessened the load by that same amount. This APPEARS to be a 2:1 because he can hold himself with half the force, but my question is: is that mechanical...

Thread 'Newton's first law?'

Some physics textbook writer told me that Newton's first law applies only on bodies that feel no interactions at all. He said that if a body is on rest or moves in constant velocity, there is no external force acting on it. But I have heard another form of the law that says the net force acting on a body must be zero. This means there is interactions involved after all. So which one is correct?

Thread 'Free fall of person in a sled to direct horizontal motion by atmospheric resistance'

Let there be a person in a not yet optimally designed sled at h meters in height. Let this sled free fall but user can steer by tilting their body weight in the sled or by optimal sled shape design point it in some horizontal direction where it is wanted to go - in any horizontal direction but once picked fixed. How to calculate horizontal distance d achievable as function of height h. Thus what is f(h) = d. Put another way, imagine a helicopter rises to a height h, but then shuts off all...
