Question

What is reduced mass?

Open in App

Solution

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.
$μ = \frac{m_{1} m_{2}}{m_{1} + m_{2}}$
