Everything falls faster than an anvil

Law I: Any body suspended in space will remain in space until made aware of its situation.
Daffy Duck steps off a cliff, expecting further pastureland. He loiters in midair, soliloquizing flippantly, until he chances to look down. At this point, the familiar principle of 32 feet per second per second takes over. However, he will not necessarily fall immediately. He may be given the chance to run (on air) back toward the precipice before he begins to accelerate downwards. He usually cannot run fast enough, and starts to fall JUST before his arms can reach the edge.
