Would a steel bar or a steel bar of the same size covered in rubber be more impactful/ inflict more damage?

Why?

The steel bar would. Depending on the rubber the rubber will absorb some of the impact

Depends on what it's hitting/what velocity.


The coefficient of friction from the rubber has the possibility of interacting with something more violently as it slows from ridiculously high speeds.

Although if they are the same dimensions like you mention, the mass of the rubber covered will he lower, so in some applications, the extra momentum could cause more damage depending on the target.


You also have to take into account what the metric of "damage" takes into account, which also coincides with what the target actually is.
