Physics drag equation
Webb2 feb. 2024 · The following equation gives the magnitude of the drag force. F D = 1 2CρfAv2 F D = 1 2 C ρ f A v 2 Where, C is the drag coefficient, which is dimensionless with values depending upon the shape of the object. (For example, C = 0.47 for a sphere and C = 0.82 for a long cylinder) ρf is the density of the fluid. v is the velocity of the object. WebbDrag force is the resistance of a fluid, the force that it applies acting opposite to the motion of an object that is moving submerge in a certain fluid. Drag = (density) * (square of the velocity) * (Drag coefficient) *(transversal area) The equation is written. F D = ½ ρ * v 2 * C D * A . We have: F D: Drag force. ρ: fluid density

Therefore, the strategy is to find the quantities that affect F, find their dimensions, and then combine the quantities into a quantity with dimensions of force. Question
Webb12 apr. 2016 · The drag equation can be written as v ′ ( t) = α v ( t) 2 for some constant α (which you have to work out: it depends on p, C D, etc.). The equation v ′ ( t) = α v ( t) 2 is a first order differential equation which you have to solve to get the function v ( t). Webb23 feb. 2005 · The drag force equation is a constructive theory based on the experimental evidence that drag force is proportional to the square of the speed, the air density and the effective drag surface area.
