This is the question that physicists all around the world are trying to answer. When they come up with one I'll be sure to get back to you. This area is primarily the work of string theorists.
AnswerI think the previous answerer misread the question. If the question had been "When and where do general relativity and quantum mechanics overlap?" then this answer would have been fine. But there is no conflict between Newton's Laws and quantum mechanics. More precisely: If you take quantum mechanics and let Planck's constant tend to 0, you get Newtonian physics. (Or special relativity - but if you then let the speed of light tend to infinity you get Newtonian physics.) In other words, classical physics is a special case of quantum physics. If you avoid doing experiments with very small or very fast things, Newton's laws will hold.I believe that is quantum mechanics, but I'm not 100%.
Classical mechanics. And if you're doing what im doing then you might also want to know that quantum mechanics describes the motion of small particles.:)
Quantum mechanics is the mathematical description of matter on an atomic and subatomic scale. It is focused around the wavefunction of a system. Wave functions contain all information about the system such as: momentum, position, angular momentum, energy, etc. This information can only be known by its respective probability distributions. The basis of quantum mechanics in the wave mechanics formulation is the Schrodinger equation, which has two forms: the time-dependent and the time-independent.Quantum mechanics is a branch of mechanics concerned with mathematical modelling of the interaction and motion of subatomic particles.
In short, it is called de Broglie wave (or matter wave). Which relates frequency and wavelength to momentum and energy. This relation then leads to group velocity which is an important part of quantum mechanics.
Newtons thrid law of motion is that every action has an opposite and equal reaction acting upon it
In the microworld the study of motion is called mechanics or classical mechanics. The study of the motion of particles in the microworld of atoms and nuclei is called quantum mechanics.
I believe that is quantum mechanics, but I'm not 100%.
- classical mechanics - motion, velocity, acceleration, inertia, forces, momentum, etc. - electricity, magnetism, and light (electromagnetism) - wave mechanics - thermodynamics - quantum mechanics - quantum electrodynamics - quantum chromodynamics - superconductivity - general and special relativity - string theory and supersymmetry - cosmology (the list goes on and on)
The main difference among both is that Classical Mechanics are all rigorously observed under the Laws of Motion of Newton, also known as the Three Laws of Mechanics; whereas the Quantum Mechanics do not observe these Laws in a fullfilling manner. For instance, the Three Laws of Motion stipulate that an object that switches behavior from rest to motion undergoes a transitional stage known as acceleration; it has been observed that when a quantum or photon is emmited by an electron, it doesn't undergo said transitional stage, but it is rather thrusted all the way into light speed. The Classical Mechanics work for objects that are primarily made of matter, while the Quantum Mechanics work for objects that can hardly be called objects, for they are primarily made of energy, or carry few or no matter at all.

There are many kinds of particles and many kinds of motion, so there is more than one answer to that question. In many cases, particle motion is explained by Newtonian mechanics. In other cases, you would need quantum mechanics or Einstein's theory of relativity, or the Maxwell equations if the particles are photons.
Quantum mechanics is the branch of physics that deals with the motion of particles by their wave properties at the atomic and subatomic levels.
Quantum mechanics explains the unpredictable nature of the electron (and of subatomic particles in general).
