TL;DR Summary
Imagine a new 'second law'→F=mV(different from F=ma,the idea from Aristotelian),and find the corresponding first,third, fourth etc laws to make this imaginary theory self-contained.
Assuming that a universe operates according to Aristotle's mechanics, that is to say, the second law of Aristotle in this universe

F=mV (V is the velocity of the object's motion)True. (Note that 'm' here does not have a dimension of mass.)

In order to obtain a logically consistent Aristotle's mechanics, how should Aristotle's first and third laws be expressed? If you feel that more laws are needed to make the entire theory self consistent, please list these laws and explain the reasons. Of course, it is also possible that only two laws are needed, such as Aristotle's first law and second law. The third law is not needed. If so, please explain the reasons

Im gratefully welcome to all kinds of ideas and hope get a complete answer:bow:🌹🌹

I'm not sure there is much you could do with that as a starting point. Velocity is frame dependent, so you require a special reference frame in which this law holds. That quantity ##F## as you've defined it is simply momentum, so what is the quantity ##ma## in this theory?

As soon as you start analysing kinematics like circular motion, it's clear that ##ma## becomes an important quantity. You can't make progress simply with a definition of momentum. You need more than that.

I'd say you cannot make any progress with that as the second law.

With that, the question can be considered as answered.

Also, please have a look at our rules. What-if questions are almost forbidden by our rules (only mainstream science, no speculations, or personal theories, no philosophy). This is because we understand ourselves as teachers who try to help students understand what is, not what could be; maybe with a bit more leash in our sci-fi forum. It is difficult enough to understand the consequences of ##F=ma## and even more difficult to understand its limits!

1. What is "another view" of basic mechanics' laws?

The "another view" refers to the perspective of classical mechanics, which is based on Newton's laws of motion and the concept of forces acting on objects. This view is often contrasted with the more modern view of quantum mechanics, which describes the behavior of particles at the atomic and subatomic level.

2. How does this "another view" differ from the traditional view of basic mechanics' laws?

The traditional view of basic mechanics' laws focuses on the macroscopic behavior of objects, while the "another view" takes into account the microscopic behavior of particles. It also incorporates the concept of quantum uncertainty, which means that the exact position and momentum of a particle cannot be simultaneously known.

3. Can the "another view" of basic mechanics' laws be applied to all physical systems?

No, the "another view" is primarily applicable to systems at the atomic and subatomic level. Classical mechanics is still the most accurate and useful for describing the behavior of larger objects, such as planets and cars.

4. What are the implications of this "another view" for our understanding of the physical world?

The "another view" of basic mechanics' laws challenges our traditional understanding of causality and determinism. It suggests that at the microscopic level, particles can behave in unpredictable ways and are subject to probabilities rather than definite outcomes.

5. Are there any practical applications of the "another view" of basic mechanics' laws?

Yes, the principles of quantum mechanics have led to the development of technologies such as transistors, lasers, and MRI machines. It also plays a crucial role in fields such as nanotechnology and quantum computing.
