Why sphere has minimum surface area for given volume?
The same volume of an object, The simplest regular tetrahedron polyhedron, calculate the surface area. The surface area is pentahedral small surface area than the regular tetrahedron Regular hexahedron surface area than the surface area is small pentahedral . . . . If it is known is N-face surface area of ​​the body, there are N +1 is smaller the surface area of ​​the surface When N tends to infinity for a long time, Serve the sphere surface. ------mecose

What force causes a leaf to fall more slowly than a penny?
We know that air resistance (or atmospheric drag) is what causes a leaf to fall more slowly than a penny. A large leaf that weighs a much as a penny has a much greater surface area than the penny, and all this surface area means that the leaf has more drag. Though the leaf and penny will be accelerated by the same amount of force (because they have the same mass), the leaf will present all that surface area to the air, and this will set up a condition of high drag.
