The escape velocity is a way of measuring the exact amount of energy needed to reach the lip of the well -- and have no energy left over for walking away. When a ball is thrown up into the air from the surface of the Earth, it does not have enough energy to escape. So it falls back down.
The American Chestnut is a large, broad tree that produces an edible chestnut. Large leaves turn yellow and brown in autumn. At least two American Chestnuts planted no more than 200' apart are required for producing chestnuts.This tree was very common before blight wiped out most of them in the early 1900's.ur pure American Chestnuts come from mature parents who have survived the blight and are producing chestnut seeds. For now, the possibility of American Chestnuts getting the blight sometime in their life is a real possibility.
The pod of the edible sweet chestnut has a sort of porcupine look to it with thin prickly spikes that point out in all directions and form a sort of thicket where you cannot see anything but the spikes.These are green while the chestnuts are forming and then turn brown when the chestnuts are mature.hen the edible chestnut is ripe, the shell opens and the nuts drop like rain. A nut is a seed of the tree, and the goal is to make a baby tree. The nuts even in their spiny hard-as-hell to pick up before they pop roll wildly on the slightest incline.
