Certainly there is a force, in this case a torque.
However when measuring the torque there is no acceleration.
Therefore the mass does not matter, the force will be the same regardless of the mass.
When performing the test, there is not supposed to be any acceleration while measuring the torque (force).
Again - a dyno test is not a race from one RPM to another.
It is supposed to be a series of discrete measurements at constant RPM (and constant Torque).
