Super-G skiers have poles that are curved to fit around the body to reduce air resistance.
This low, air resistance creates drag, so the station is constantly slowing down and losing altitude at the rate of about two miles of altitude every month.

And the hot plasma can also heat up and expand the upper layers of the atmosphere, causing satellites in low orbits to encounter more air resistance and lose altitude.
All that was needed to make a mechanical energy-storage system was a good enough rotational seal, so the flywheel could spin freely inside a vacuum chamber with no air resistance.
Mr Haldane uses the analogy of dogs, such as border collies, which are very reliable catchers of Frisbees without being aware of the complex calculations (wind speed, air resistance, etc) that might be involved.
By changing the angle of its wings and its body, the moth was able to create a delicate balance between the thrust pushing it forwards, the drag - or air resistance - pushing against it, and the lift keeping it in the air.
The intervening weeks will be spent in a manoeuvre called aerobraking, which involves using the air-resistance of the thin Martian atmosphere to change the elliptical initial orbit into a circular one from which the planet's surface can be examined in detail.
Giuseppe Marani, said NATO pilots encountered only light resistance from Yugoslav air defenses and suffered no losses.

But rebel efforts to gain ground in and around major cities including Damascus have been met by stiff resistance and increasingly destructive air strikes.

Although swimmers and sprinters face no resistance beyond water and air, peak-performance feats in other sports must face strong defenses, which only improve as each sport gains sophistication.
Chambers said all convoys are escorted, and there is also air support in areas of high insurgent resistance.
Gravity waves form when air traveling up and down in the atmosphere meets resistance.

The technology works by reducing frictional resistance between the vessel hull and seawater using air bubbles along the bottom of the ship.

The Turks, aided by our air power, would make short shrift of any Iraqi armed resistance to their marching into northern Iraq.
When its infantrymen meet resistance, they either slide round it or call in the air force or the artillery.
The air-raids have had the predictable effect of galvanising support for the resistance and steeling Lebanese resolve to tough it out.
Barger has continually expressed firm resistance toward any deal, despite attempts to keep JetBlue up in the air as a takeover target.

Unfortunately, because of the nature of air circulation, any downward-pointing force created aerodynamically generates a backward-pointing resistance in the process just as an increase in the lift of an aircraft wing as the flaps are lowered for take-off or landing creates more drag in the process, forcing the pilot to open the engine throttles to overcome the extra wind resistance.
Israel responded immediately with an air strike on the southern Gaza town of Rafah, killing several leaders of the Popular Resistance Committees whom the Israelis accused of planning the attack.
Four days of cross-border violence was triggered by an Israeli air strike on Friday that killed a senior leader of the militant group, the Popular Resistance Committees (PRC), who Israel said had been planning an attack.
Meanwhile, four Palestinian members of the Popular Resistance Committee, a militant group, were critically injured as a result of an Israeli air force strike after launching rockets at Israeli territory, security forces in Gaza told CNN.
British troops, with the support of coalition air power, have been pushing steadily into Basra since shortly after the start of the war, facing fierce resistance from Iraqi regular and irregular troops.
