A series of dominos are stood on end close together so that when one domino is tipped over it
will set off a chain reaction of collisions knocking over all the other dominos. Which describes
the state of each domino before any are knocked over?
A. Unstable and not in equilibrium
B. Stable equilibrium
C. Stable, but not in equilibrium

Solution
Since the dominos are standing still before any are knocked over, so they are in equibrium(net
force on them = 0). And tipping one domino knocks over all other dominons, so they are in
unstable equiblibrium(they have potential energy when they are upright).
