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!

FAQ: An interesting question about another view of baisc mechanics'laws

What is the significance of revisiting basic mechanics laws from another perspective?

Revisiting basic mechanics laws from another perspective can provide deeper insights and a better understanding of fundamental principles. It can also reveal new connections between different areas of physics, potentially leading to novel applications and innovations.

How can alternative views of mechanics laws impact modern physics?

Alternative views can challenge existing paradigms and stimulate new theoretical developments. They can lead to refinements in models and simulations, improve the accuracy of predictions, and inspire experimental investigations that might confirm or refute these new perspectives.

Are there any historical examples where reinterpreting basic mechanics laws led to significant discoveries?

Yes, one notable example is the development of quantum mechanics. The reinterpretation of classical mechanics principles to account for atomic and subatomic phenomena led to groundbreaking discoveries and the establishment of an entirely new branch of physics.

What are some common misconceptions about basic mechanics laws that alternative views try to address?

Common misconceptions include the oversimplification of forces, the neglect of relativistic effects at high velocities, and the assumption that classical mechanics can fully describe all physical phenomena. Alternative views often aim to correct these misconceptions by incorporating more comprehensive models.

How can educators incorporate alternative views of mechanics laws into their teaching?

Educators can incorporate alternative views by presenting multiple interpretations of fundamental concepts, encouraging critical thinking, and discussing the historical and philosophical context of mechanics laws. Utilizing diverse teaching methods, such as simulations and problem-based learning, can also help students grasp these alternative perspectives.
