Sentences with phrase «drag force»

The phrase "drag force" refers to the resistance or backward force that acts on an object moving through a fluid, such as air or water. It happens because the fluid pushes against the object, making it harder for the object to move forward. Full definition
The point of the practice is in a long dragging force.

As you rotate your hand in the air stream, you vary the amount and direction of the lift and drag forces acting on your hand.
At the moment of full inflation, the parachute is going 1.8 times the speed of sound or nearly 1,300 miles an hour, and generating nearly 35,000 pounds of drag force - drag that would be necessary to help slow a payload down as it was entering the Martian atmosphere.
CVT - equipped Versa Note models include Nissan's first - ever Active Grille Shutter, which limits the amount of air entering the engine compartment, reducing drag force by 0.01.
But there may be a way to cut drag force by almost 30 %, according to computer simulations of turbulent ocean - water flows reported in the 19 May issue of Science by mechanical engineer Yiqing Du of the Massachusetts Institute of Technology and applied mathematician George Karniadakis of Brown University.
Previous models of the dandelion fruit considered that each parachute filament acts independently, and that the total drag force supplied by the parachute can be found by adding up each of these contributions.
Attached and condos will eventually feel the same dragging force; however, when that actually happens is anyone's guess (and there's just no evidence of it yet).
In the Earth Surface Dynamics Lab at the California Institute of Technology (Caltech) the behavior of rivers is modeled through the use of artificial rivers — flumes — through which water can be pumped at varying rates over a variety of carefully graded sediments while drag force and acceleration are measured.
Friction between the atmosphere and materials passing through it, known as drag force, offers the only natural means for culling detritus left in orbit by space launches.
«This study significantly improves our understanding of the energetic cost of large whale entanglement drag forces.
What I had meant, (and what I had assumed Bannon meant although I haven't parsed the paper in enough detail to tell), was the situation when the droplets have reached terminal velocity — the upward drag force on the droplet has to be balanced by a downward reactive force on the air equal to the weight of the droplets.
Model S aerodynamics are so optimized that the total aerodynamic drag force experienced by the car — which is significantly larger in frontal area — is almost the same as a Roadster for a given speed.
Established 3D models in Solid Works and CATIA for Automobile contour based on Model car's point cloud data to analyze Car drag force and turbulence.
The lift and drag forces on a golf ball are very sensitive to dimple depth: a depth change of 0.001 inch can produce a radical change to the ball's trajectory and the overall distance it can fly.
The rising gas pressure changes the drag force on the orbiting dust, causing the clump to grow and better heat the gas.
A resulting drop in its density is also cutting its drag force, thereby increasing the lifetime of orbiting trash (including pieces in that heavily populated band at 800 to 1,000 kilometers).
She also spent time in Langley's wind tunnels, making painstaking adjustments to whittle down drag forces.
To calculate that drain, the scientists, in a separate experiment, towed three types of fishing gear from a skiff, using tensiometers to measure the drag forces acting on Eg 3911.
Working with colleagues from the Center for Coastal Studies and NOAA Fisheries, van der Hoop used a load cell to measure the drag forces on various types of fishing gear collected from past right whale entanglements.
Generally, lift is directed up, perpendicular to the drag force.
Saltating grains travel elongated, asymmetric trajectories: Rising relatively steeply off the bed, their path is then stretched downwind as they are accelerated by drag forces.
However, as the Clouds approached our Galaxy, the Milky Way's corona exerted a drag force on both of them.
The cyclist himself accounts for 72 per cent of the drag force, with his legs generating most of that.
Because the light field acts as a viscous force, we dubbed the combination of laser beams used to create the drag force «optical molasses.»
An analysis of the gel showed that the implants seemed to flatten the bullets and make them wider, increasing their drag force and slowing them down.
The technology also should be safe, as cutting electricity to the rotor stops the propulsion and leaves only a drag force.
And that drag force is probably much less significant than the drag the ship's hull experiences moving through water, says Jeff Eldredge, a fluid dynamicist at the University of California, Los Angeles.
In our models we consider collisions, direct radiation pressure, and drag forces, i.e. the actual physical processes operating in debris discs.
This higher factor under overrun was chosen, first, because the engine's drag force is lower than its maximum torque and, second, because this configuration serves to stabilise the car, preventing it from swerving or turning under load change in bends, as now brake force is applied more evenly on both wheels when the driver suddenly takes back the gas pedal.
For example, the drive belt for the a / c compressor, comes with an independent clutch automatically disconnecting the compressor as soon as the driver switches off the air conditioning and thus reducing the drag forces generated by the compressor to a minimum.
