For two given bodies, one with mass and the other with mass , the reduced mass is expressed as: The force on the reduced mass is given by the force between the two bodies. After solving this equivalent one-body problem, the two-body problem can be solved for the motion of the two initial bodies or point particles.
What do you understand by the reduce mass How is the two body problem reduce to a single body problem?
How is the two-body problem reduce to a single body problem?
…in a vibrating or rotating two-body system. The equations of motion of two mutually interacting bodies can be reduced to a single equation describing the motion of one body in a reference frame centred in the other body.
What is reduced mass of a two-body system?
Definition: When two bodies in relative motion are acted upon by a central force involving Newton's law then the system can be replaced by a single mass called the reduced mass.
What do you understand by the reduced mass?
reduced mass, in physics and astronomy, value of a hypothetical mass introduced to simplify the mathematical description of motion in a vibrating or rotating two-body system. … The moving body then behaves as if its mass were the product of the two masses divided by their sum. That quantity is called the reduced mass.
What is the reduced mass Why is it always less than the mass of either particle?
It is less than the mass of a single particle, because the interparticle distance accelerates more than if the force acted on one particle alone. This is for the physical meaning in classical mechanics.
How is reduced mass derived?

Who Solved the 2 body problem?
The two-body problem consists of determining the motion of two gravitationally interacting bodies with given masses and initial velocities. The problem was first solved by Isaac Newton in 1687 using geometric arguments.
Why do we use the reduced mass?
We use reduced mass to make the maths simpler, and to make the equations look more like single-body equations… which are easier to use and understand. The problem, if we did not use it, would be that the maths would be harder. Why do harder maths than you have to? You should try not using reduced mass and see.
Why do we need reduced mass?
We use reduced mass to make the maths simpler, and to make the equations look more like single-body equations… which are easier to use and understand. The problem, if we did not use it, would be that the maths would be harder. Why do harder maths than you have to?
