This pattern consists of two wake lines that form the arms of a chevron, V, with the source of the wake at the vertex of the V. When given one of the three representations of motion, students will be able to create quantitative position vs.Time graphs, velocity vs. Write an equation in standard form when you're given two points on a line. The period, speed and acceleration of a satellite are only dependent upon the radius of orbit and the mass of the central body that the satellite is orbiting. Wake vortices are formed any time an aerofoil is producing lift. (rotation and shear) and wake vortex added-mass (cf. Dabiri,. Numerical simulations of the near wake of a sphere moving in a steady, horizontal motion through a linearly stratified fluid at Re = 1000.
