FD = 1 2CρAv2, where C is the drag coefficient, A is the area of the object facing the fluid, and ρ is the density of the fluid. (Recall that density is mass per unit volume.) This equation can also be written in a more generalized fashion as FD = bv2, where b is a constant equivalent to 0.5CρA.
25 wrz 2022 · For example, in Figure 1.2, if you want to work out how long (I) convert from mis to m/h, then divided by 1000 to convert from mlh to km/h f.it takes to move a distance (s) at a given speed (v), covering I in Figure 1.2 leaves (as there are 1000 m in 1 km). or distance divided by speed.

Understand that y = mx + c represents a linear relationship. Determine the slope and intercept of a linear graph. Useful equations: F Δt = m Δv shows the impulse of a force is equal to the change in momentum. y = mx + c shows why the intercept should be zero.
