  2. Magnus effect - Wikipedia

    en.wikipedia.org/wiki/Magnus_effect

    Streamlines for the potential flow around a circular cylinder in a uniform flow. The flow pattern is symmetric about a horizontal axis through the centre of the cylinder. At each point above the axis and its corresponding point below the axis, the spacing of streamlines is the same so velocities are also the same at the two points.

  3. Lift (force) - Wikipedia

    en.wikipedia.org/wiki/Lift_(force)

    An airfoil is a streamlined shape that is capable of generating significantly more lift than drag. [11] A flat plate can generate lift, but not as much as a streamlined airfoil, and with somewhat higher drag. Most simplified explanations follow one of two basic approaches, based either on Newton's laws of motion or on Bernoulli's principle.

  4. Drag equation - Wikipedia

    en.wikipedia.org/wiki/Drag_equation

    Consequently when a body is moving relative to a gas, the drag coefficient varies with the Mach number and the Reynolds number. The analysis also gives other information for free, so to speak. The analysis shows that, other things being equal, the drag force will be proportional to the density of the fluid.

  5. Drag (physics) - Wikipedia

    en.wikipedia.org/wiki/Drag_(physics)

    In supersonic flow regimes, wave drag is commonly separated into two components, supersonic lift-dependent wave drag and supersonic volume-dependent wave drag. The closed form solution for the minimum wave drag of a body of revolution with a fixed length was found by Sears and Haack, and is known as the Sears-Haack Distribution .

  6. Stokes' law - Wikipedia

    en.wikipedia.org/wiki/Stokes'_law

    Creeping flow past a falling sphere in a fluid (e.g., a droplet of fog falling through the air): streamlines, drag force F d and force by gravity F g. At terminal (or settling) velocity , the excess force F e due to the difference between the weight and buoyancy of the sphere (both caused by gravity [ 7 ] ) is given by:

  9. Exercise (mathematics) - Wikipedia

    en.wikipedia.org/wiki/Exercise_(mathematics)

    A distinction between an exercise and a mathematical problem was made by Alan H. Schoenfeld: [2] Students must master the relevant subject matter, and exercises are appropriate for that. But if rote exercises are the only kinds of problems that students see in their classes, we are doing the students a grave disservice. He advocated setting ...
