  The motion of a classical test particle moving on a 4-dimensional brane
embedded in an $n$-dimensional bulk is studied in which the brane is allowed to
fluctuate along the extra dimensions. It is shown that these fluctuations
produce three different forces acting on the particle, all stemming from the
effects of extra dimensions. Interpretations are then offered to describe the
origin of these forces and a relationship between the 4 and $n$-dimensional
mass of the particle is obtained by introducing charges associated with large
extra dimensions.
