Reduced mass and its applications - Physics Stack Exchange
2021年10月25日 · Reduced mass is a physical equation used for two (or more) objects in motion about each other, vibrating or rotating due to their own internal forces, while both objects are being subjected to an external force that translates them. It defines the "center point" behavior of the system of two objects as viewed by the external force.
newtonian mechanics - What is the physical meaning of reduced …
2016年4月27日 · $\begingroup$ "In physics, the reduced mass is the "effective" inertial mass appearing in the two-body problem of Newtonian mechanics. It is a quantity which allows the two-body problem to be solved as if it were a one-body problem."

Centre of mass and reduced mass in classical mechanic
2024年4月27日 · $\begingroup$ @MattHanson Reduced mass has nothing to do with the position of the center of mass. Things go the other way around. Things go the other way around. Since the equation of motion for the relative position does not depend on the position of the center of mass, in many cases, we can simplify the analysis by choosing the origin as ...
Derivation of reduced mass - Physics Stack Exchange
2019年12月18日 · Note that if m1>>m2 reduced mass is almost the same as m2. This the motion of two body system consists of its CM and motion around it. The motion around it can be described in terms of a single, reduced mass moving around fixed center.
How to represent the reduced mass in the curved space form, …
2021年5月17日 · Then, the differential equations describing the orbits (see (1), (2) and (3) in image) have the reduced mass terms to represent combined motion of both the masses. In these equations, if we assume that the central mass is very large compared to the planet mass, then the planet mass ( m2 ) term vanishes and orbit equations become dependent only ...
How does the orbital motion of reduced mass tell us how the …
2020年12月9日 · My interpretation of eqn (29) is that the position vector $\vec{r}$ of the reduced mass is also the relative distance between the 2 masses, therefore if the reduced mass is undergoing elliptical motion about its centre of mass, it is equivalent to taking the reference frame one of the objects in the binary system and measuring the position ...
newtonian mechanics - Two body particle problem with reduced …
The concept of this fictitious particle with the reduced mass is extremely useful, because as have shown on mathematical level you can think about this problem (when neglecting the uniform motion of the center of mass) as the motion of only one particle in …
Reduced mass in quantum physics (Hydrogen Atom)
I've gone through an intermediate classical mechanics course, and in solving the two-body problem, we reduce it to a one-body between a larger stationary mass, and a smaller reduced mass. Most solutions I've seen of the hydrogen atom simply neglect the movement of the nucleus.
Why does reduced mass help when talking about two body …
2015年1月14日 · Yeah, it's mainly a mathematical simplification. The equations of motion for the two-body problem (after simplification) look very much like the equations of motion for a single body orbiting in a fixed potential, and so we can treat the problem this way, although we have to use the reduced mass instead of the mass of either of the original bodies.
