The drag is directly related to the mass of the flow passing in front of the aircraft. Drag also depends in complex ways on two other properties of air: its viscosity and its compressibility. These factors affect the wave drag and skin friction described above.
What factors influence resistance class 8?
Lift and drag also vary directly with air density. Density is affected by several factors: pressure, temperature and humidity. At 18,000 feet, the air density is half that at sea level.
What factors affect lift and drag?
The resistance on a solid, rigid object is not affected by the mass of the object. However, drag is only that portion of the force on the object that is due to the fluid. The net force on the object is of course affected by the mass of the objects, assuming gravity is one of the forces on the object.
How does mass affect drag?
Lift and drag also vary directly with air density. Density is affected by several factors: pressure, temperature and humidity. At 18,000 feet, the air density is half that at sea level.

What are the four main factors that affect drag?
Some factors that affect the magnitude of drag (drag) include the size and shape of the object, the speed of the object and the air, and other properties of the air such as: B. their viscosity, mass and compressibility.
What factors affect lift and drag?
Lift and drag also vary directly with air density. Density is affected by several factors: pressure, temperature and humidity. At 18,000 feet, the air density is half that at sea level.
Does temperature affect drag?
We therefore have rho=P/r.T, which tells us that at a given pressure, drag is inversely proportional to temperature. Therefore, air resistance decreases with increasing temperature.
Does drag increase with mass?
Air resistance increases with liquid density (ρ). More density means more mass, which means more inertia, which means more resistance to gapping. The two quantities are directly proportional. The resistance increases with area (A).
Does the mass of the object affect drag?
The heavier the weight, the faster the object’s speed (due to gravity), causing the object to collide with more air molecules per second and therefore slightly increasing the amplitude of the drag force on the object.
How is drag related to mass?
The motion of a falling object can be described by Newton’s second law of motion, force (F) = mass (m) times acceleration (a). … The drag power depends on the square of the speed. So as the body accelerates, its speed (and drag) increases. It will reach a point where the resistance is exactly equal to the weight.
Do heavier objects have more drag?
The upward drag force is the same while the weight of the heavier object is greater than the weight of the lighter object and hence the drag force. Therefore, the heavier object must accelerate downwards to eventually reach a higher terminal velocity than the lighter object.
