... A wooden block weighs 100 N, and is sitting stationary on a smooth horizontal concrete surface. The coefficient of static friction between wood and concrete is 0.2. A 5 N horizontal force is applied to the block, pushing toward the right, but the block does not move. What is the force of static fric ...

... Lofted Vehicle Body with Tapered Tail For design #2, a lofted vehicle body with smoothly-transitioning body curves was devised. A drag coefficient of 0.12627 resulted from this design despite a larger surface area than design #1, which is likely due to its much lower body length at 3.14m (and hence, ...

Drag (physics)
In fluid dynamics, drag (sometimes called air resistance, a type of friction, or fluid resistance, another type of friction or fluid friction) refers to forces acting opposite to the relative motion of any object moving with respect to a surrounding fluid. This can exist between two fluid layers (or surfaces) or a fluid and a solid surface. Unlike other resistive forces, such as dry friction, which are nearly independent of velocity, drag forces depend on velocity.Drag force is proportional to the velocity for a laminar flow and the squared velocity for a turbulent flow. Even though the ultimate cause of a drag is viscous friction, the turbulent drag is independent of viscosity.Drag forces always decrease fluid velocity relative to the solid object in the fluid's path.
