Query: Motion in gauge theories of gravity   A description of motion is proposed, adapted to the composite bundle
interpretation of Poincar\'e Gauge Theory. Reference frames, relative positions
and time evolution are characterized in gauge-theoretical terms. The approach
is illustrated by an appropriate formulation of the familiar example of orbital
motion induced by Schwarzschild spacetime.
