*Fr.: masse réduite*
The "effective" → *inertial mass* appearing in the
→ *two-body problem*
of → *Newtonian mechanics*.
The reduced mass is a quantity which allows the two-body
problem to be solved as if it were a one-body problem.
For the masses *m*_{1} and *m*_{2}, it is given by
the ratio μ = *m*_{1}*m*_{2} /
(*m*_{1} + *m*_{2}). The value of μ is generally smaller
than *m*_{1} and *m*_{2}. The larger the difference between
the two masses, the closer μ will be to the smaller mass. If the particles are of
equal mass, μ is half the mass of either. → *reduce*; → *mass*. |
