They found that the effects of gravity and drag combine to influence the event.
Therefore as the bread falls to the ground it only has the opportunity to achieve half a rotation before reaching the floor, thus landing butter-side down.
Studying dinosaur bones and physiology can only teach us so much about how dinosaurs actually walked the Earth. Because dinosaurs called theropods are related to modern birds, a few researchers thought they could study how they walk using chickens.
Theropods include dinosaurs like the Tyrannosaurus and Velociraptor, but they also ranged in size all the way down to tiny chicken-sized raptors covered in feathers. Theropods and modern birds also both have spongy air-filled bones, wishbones, and feathers and lay eggs and watch over them.
