Hello Perok I thought I was beginning to understand some basic concepts in Newton’s physics and differential and integral calculus i.e. the concept of continuity and how it affects differentiability, but apparently my understanding is totally wrong. If you have the time, could you clarify...

I still fail to see the logic behind the differential and integral calculus that was demonstrated on PF using Isaac Newton’s non-uniform gravitational acceleration function ##f \left (r \right) = \frac {2GM} {r^2}##, and its derived non-uniform velocity function ##f^{'} \left (r \right) = \frac...

According to the thread posted by Ibex the only mathematics need or required for the solution to this problem is Newton's equation for gravitational acceleration, and the calculus that will solve for velocity as a function dependent on time. Ibex states after you solve for velocity as a function...

@erobz Thanks for the interest. I am just in the act posting a question. can I get back to you about working out the math later on. Thanks rb75

@Wrichic Basu Hi thanks for the help. I would be glad to post you a screenshot Wrichic Basu, if you could please explain how I would do it. I'm new to PF and am very incompetent using the features in this editor. I've already been scolded once for copying and pasting text.

Thanks for the reply. The equations seem to be displayed properly. When I view the equations in the my preview mode, the second equation is displayed improperly, the small letter g in the scond equation is displayed improperly in the form of a capital letter. Do you know if there's any way...

I wrote the following equations: The first was written using hash tag delimiters, and the second equation was written using dollar sign delimiters . Could you please let me know if these equations have displayed properly in this post. This equation was written using hash tags delimiters ##a =...

When writing equations in La Tex, if I a enter a capital letter to represent a variable in the first equation I write, if I use that same letter in small form when writing a different equation, after examining the equation in preview mode, La Tex by default always displays the small letter in...

I had originally thought that Newton’s equation for gravitational acceleration was the only equation that was needed for this problem. The only reason I included Newton’s equation for gravitational force and the 2nd Law of motion and momentum, was because I had received a reply regarding a...

Hello Ibex, thanks for taking the time to reply to my question concerning the mathematics used to calculate the continually changing non-uniform displacement, velocity, acceleration and jerk that is produced by a gravitational attractive force at any instantaneous point in time. I'm glad you...

It's been more than 60 years since I attended high school, and I am trying to learn and understand concepts in Newton's physics that were not taught and were not part of the school curriculum during the 1950's. It is my understanding that the current mathematics taught and used in our...
