What are examples of drag?
Air resistance is an example of the drag force , which is force that objects feel when they move through a fluid (liquid or gas)….Drag.
| Object | Drag Coefficient (C) |
|---|---|
| Skydiver (feet first) | 0.70 |
| Bicycle | 0.90 |
| Skydiver (horizontal) | 1.0 |
| Circular flat plate | 1.12 |
Does the acceleration due to the force of drag depend on mass?
We can do a little algebra and solve for the acceleration of the object in terms of the net external force and the mass of the object (a = F / m). The drag force depends on the square of the velocity. So as the body accelerates its velocity (and the drag) will increase.
Why does drag force happen?
Drag is the aerodynamic force that opposes an aircraft’s motion through the air. Drag is generated by the difference in velocity between the solid object and the fluid. There must be motion between the object and the fluid. If there is no motion, there is no drag.
What are the three major factors that affect lift?
What Factors Affect Lift? The size and shape of the wing, the angle at which it meets the oncoming air, the speed at which it moves through the air, even the density of the air, all affect the amount of lift a wing creates.
What does lift depend on?
Lift depends on the density of the air, the square of the velocity, the air’s viscosity and compressibility, the surface area over which the air flows, the shape of the body, and the body’s inclination to the flow.
Why do thicker wings produce more lift?
The basic rule of thumb for camber line versus lift is that the more curve there is, the more lift an airfoil will generate. That’s one reason why a really fat wing generates more lift than a thin one.
Do thicker airfoils produce more lift?
The airfoils have been designed and analyzed theoretically and verified experimentally in The Pennsylvania State University low-speed, low-turbulence wind tunnel. The effect of roughness on the maximum lift increases with increasing airfoil thickness and decreases slightly with increasing maximum lift.
