Kepler
WebKepler's third law states that square of period of revolution (T) of a planet around the sun, is proportional to third power of average distance r between sun and planet i.e T 2 = K r 3 … WebBy the product rule for differentiation d d t ( r × v) = v × v + r × a = 0 since a is in the same direction as r by equation (3). Here the symbol × represents the vector cross-product. Thus, the vector h = r × v is a constant versus time. It follows that r and v lie in the plane orthogonal to h, i.e. the planet moves in a plane. dunklin daily democrat newspaper
