You mentioned here it's equal for the entire orbit.

You said, "Argument is a set of reasons or reasoning". And I say, " That's what all I am doing now...."

Astronomy/Astrophysics

23 Mar 2025 06:06

So, I am not reasoning to your question, am I?

Astronomy/Astrophysics

Classical mechanics include vast concepts of physics. But all I wanted to do is to mention the 'Newton's Gravitational model' only, not any other topics

Astronomy/Astrophysics

23 Mar 2025 06:04

The term classical mechanics is used to refer to that part of physics that don't include relativity and Quantum

Astronomy/Astrophysics

23 Mar 2025 06:03

That would include bio and chem

Astronomy/Astrophysics

23 Mar 2025 06:03

Or can i say Science instead?

Astronomy/Astrophysics

23 Mar 2025 06:02

How is Newton's law of gravitation not a part of Classical Mechanics?

Astronomy/Astrophysics

23 Mar 2025 06:00

When we use newtonian model for gravity, yes

Astronomy/Astrophysics

23 Mar 2025 05:58

According to Newton, Yes

Astronomy/Astrophysics

23 Mar 2025 05:58

We can use calculations. But I said that, the total energy is zero, if they are equal in magnitude. Knowing their magnitude using formulae is secondary

Astronomy/Astrophysics

23 Mar 2025 05:55

Is the change of velocity over time, Is acceleration a part of mechanics?

Astronomy/Astrophysics

23 Mar 2025 05:54

I have told it. I have confessed that it was wrong too

Astronomy/Astrophysics

23 Mar 2025 05:53

Are velocity and speed a part of mechanics?

Astronomy/Astrophysics

23 Mar 2025 05:51

I am not talking about the newton's contributions to mechanics, which is also a part of classical mechanics. I am accessing the Newton's gravitational model, without touching his mechanics. That's why don't choose "classical mechanics"

Astronomy/Astrophysics

23 Mar 2025 06:08

Is the total energy of the ISS zero though.?

Astronomy/Astrophysics

23 Mar 2025 06:06

Reframe this.
Did not understand

Astronomy/Astrophysics

23 Mar 2025 06:06

Anyway. If there are better terms to use why not use them.
It will avoid confusion.
That's all I'm saying

Astronomy/Astrophysics

23 Mar 2025 06:05

That's not an argument, that's a question. An argument is a set of reasons or reasoning.

Astronomy/Astrophysics

23 Mar 2025 06:04

That's my argument Mr Admin

Astronomy/Astrophysics

23 Mar 2025 06:03

Then physics would include relativity and quantum as well

Astronomy/Astrophysics

23 Mar 2025 06:03

It is also a part of physics. Can i say Physics, instead of classical mechanics?

Astronomy/Astrophysics

23 Mar 2025 06:01

Isn't that a statement of mechanics?

Astronomy/Astrophysics

23 Mar 2025 06:00

Can you then say for the ISS.
Its change of velocity over time is equal to the gravitational force acting on it per unit mass?

Astronomy/Astrophysics

23 Mar 2025 05:58

Is gravitation a force?

Astronomy/Astrophysics

23 Mar 2025 05:56

Can you say acceleration is the net force per unit mass from F = ma
Which is Newton's second law of motion?

Astronomy/Astrophysics

23 Mar 2025 05:54

How do we know they are equal.

Astronomy/Astrophysics

23 Mar 2025 05:53

I said, i don't need the formula to say the total energy is zero, if the kinetic and potential energies are equal in magnitude.

Astronomy/Astrophysics

23 Mar 2025 05:52

Ok how are we going to settle this.
As far as I know everything in physics can be quantified.
So things like Kinetic and Potential Evergy can be calculated.
What do you mean by formula is not required.
.
.
How do you come to the conclusion that they are equal?

Astronomy/Astrophysics

23 Mar 2025 05:49

You don't need a formula for this problem. The total energy is the sum of Kinetic and potential energies (which are always positive and negative respectively ) if they are equal to magnitude (and eventually opposite in direction), the total energy becomes zero.
