The laws of motion cannot be derived purely from calculus, as they are fundamentally physical laws based on empirical observation and experimentation. While calculus can be used to express and develop these laws mathematically, their origins lie in physical principles rather than mathematical foundations. The formulation of these laws requires postulation based on real-world phenomena. Therefore, understanding the laws of motion involves both mathematical representation and physical experimentation. Ultimately, the relationship between calculus and the laws of motion is one of application rather than derivation.

How do you derive the laws of motion using Calculus from scratch
 
Physics news on Phys.org
You can't. The laws of motion are physical laws, independent of the foundations of mathematics. The laws can be stated in mathematical form and developed using mathematics, such as calculus.

But, they have to be postulated through observation and experiment.
 
First of all, I thought there were 3 Newton's laws of motion.

Second of all (ironically speaking), the Newton's 2nd law states that F = ma. We can say that a is equivalent to the derivative of velocity wrt time. The derivative, in this case, uses calculus.
 
I do not understand which 4 laws are supposed to derive but the work energy theorem is usually derived from the 2nd Newton; as well as the angular momentum theorem is also a theorem and it is derived.
 

Thread 'Using energy principles to find equilibrium depth of floating object'

For fun I was trying to use energy considerations to determine the depth to which a solid object will sink in a fluid to reach equilibrium. The first approach that I tried was just to consider the change in potential energy of the block and the fluid as the block is lowered some unknown distance d into the fluid similar to what is shown in the answer to this post. Upon taking the limit as the vessel's cross sectional area approaches infinity I have an extra factor of 2 in the equilibrium...

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 'A remark on problem about trajectory of a projectile in the atmosphere'

This is just to share some teaching experience. A problem about trajectory of a projectile in the atmosphere is very well known. The trajectory has a vertical asymptote. This fact is easy to obtain by using the stability theory. Consider equations of motion. Let ##\boldsymbol v=v_x\boldsymbol e_x+v_y\boldsymbol e_y## be the velocity of the projectile relative the standard Earth fixed frame ##xy## with ##y## directed upwards. The second Newton ##m\boldsymbol {\dot v}=m\boldsymbol g-\gamma...
