A copper coin resting on a piece of cardboard is placed on a beaker as shown in the diagram. When the cardboard is rapidly removed, the coin drops into the beaker.



The two properties of the coin which best explain its fall are its weight and its

temperature
electrical resistance
volume
inertia

Although I can't see your diagram, the answer is inertia.  It's the same as those douchebags who yank a table cloth and leave the silverware and such still on the table.

There is no diagram. The first three properties are irrelevant.

The coin falls because it was not moving ("body at rest") and its supporting cardboard was removed so quickly that its inertia kept it from moving along with the cardboard. So it fell straight down from its resting position.

The answer is Inertia.

inertia and volume.
inertia for reasons above, volume because in conjuction with weight it controls density and explains why the coin does not simply float.
