SUMMARY
The force required to move a piano on a smooth, clean track is primarily determined by overcoming the friction in the bearings of the wheels supporting the piano's weight. Assuming no binding in the track and that it is made of a hard material, the rolling resistance will also play a role, but the main factor is the frictional force in the bearings. This friction can be calculated using the coefficient of friction specific to the materials involved.
