because the area of contact of eraser in rolling is less than the area of contact of eraser in sliding
Why is it easier to tear a paper towel off of a full roll than off of a mostly used roll?
A full roll is very sturdy, while a mostly used roll is more fragile. Therefore, when you go to pull the paper off the full roll, it comes off easily without you having to steady the roll...but if you want to tear paper off a mostly used roll, you'll have to hold the roll down before you tear it off so the roll doesn't fall. Basically, because a full roll is sturdier than a mostly used roll.

It would be increased because the loss due to friction would be reduced.
Which is easier to do- push a drum across the floor in an upright position or roll on its side?
It is easier to roll a drum on its side across the floor due to the reduced surface area in contact with the ground, resulting in less friction compared to pushing it upright. Rolling on its side also allows for smoother movement and better control.
Why is it easier to roll than to slide?

What solid shapes can slide and roll?
Solid shapes that can slide and roll include cylinders, spheres, and cones. Cylinders can roll along their curved surface, while spheres can roll in any direction due to their uniform curvature. Cones can roll on their circular base, although their movement is limited to a specific direction. In contrast, cubic shapes can slide but do not roll effectively due to their flat surfaces.
