Air resistance refers to the force that opposes the motion of an object as it moves through the air. It's like the resistance or pushback that air gives to objects trying to move forward.
Full definition

air resistance while running and therefore burns fewer calories than a runner that is running on solid ground.
Note also hill grade, outside air temperature (cold air is more dense and
thus air resistance is higher) and wind speed and direction when determining the top speed.

using air resistance are also popular these days.

minimal air resistance, which contributes to low fuel consumption, outstanding driving skills and top - class comfort.
It's
like air resistance of cars at a velocity of 15 mph against the forces necessary to accelerate the car to 30 mph.
The combination of up to 20 per cent more power,
reduced air resistance and a reduction in weight also result in remarkable driving dynamics.
The errors in the projections were due to applying a model that was valid for special cases under laboratory conditions, but did not take into account factor
of air resistance.
The 2012 Nissan GT - R's advanced VR38DETT 3.8 - liter twin turbo V6 now produces 530 horsepower (versus the previous 485 horsepower) and 488 lb - ft of torque (versus the previous 434 lb - ft)-- a result of modifying the boost pressure of the turbocharger, valve timing and air mixture ratio, and through reducing intake
air resistance by enlarging the inlet pipe diameter.
The skater crouches forward (as if he was skating in a squat position) to reduce drag caused by
air resistance on the front of his body, and to help him balance.
The reduction
in air resistance increases the efficiency of cycling by about 90 %, allowing for speeds up to 40 km / hr.»
Utilising key advanced technologies and engineering learned from the Hyundai N, Hyundai Motor has
minimized air resistance through wind tunnel aerodynamic testing and created ideal weight distribution with a low centre of gravity design.
The 2012 Nissan GT - R's advanced VR38DETT 3.8 - liter twin turbo V6 now produces 530 horsepower (versus the previous 485 horsepower) and 448 lb - ft of torque (versus the previous 434 lb - ft)-- a result of modifying the boost pressure of the turbocharger, valve timing and air fuel ratio, and through reduced intake
air resistance created by enlarging the inlet pipe diameter.
Rob Arthur
studied air resistance at 538, using MLB's own technology, and that led him to the conclusion that the baseballs are likely different and in a way that is changing how they are coming off the bat.
The straight air intake port ends in a sharper air intake throat, reducing
air resistance at all stages of air intake to the engine, improving cylinder tumble flow for faster, more efficient combustion and suppressing engine knocking.
As fuel economy and carbon emissions become more important to car buyers, manufacturers have identified cutting
air resistance as a cost - effective way to improve these figures and so boost their product's appeal.
As a result, two objects dropped on Earth's surface should accelerate at the same rate (
neglecting air resistance), even if they have different masses or are made of different materials.
Experiments in wind tunnels have revealed the total drag experienced by skiers, but have not provided precise data on which parts of the body cause the most
air resistance when adopting the full - tuck position.
The main concern would be frictional losses through the powertrain and wheels, as well as the energy lost
fighting air resistance.
On account of the sharpness of the angle of advance presented by the forward planes it is impossible to obtain any higher speed when the machine is in the air, as the
great air resistance encountered by the aeroplane when flying at so sharp an angle consumes the entire horse - power.
The concept 2 rowing machine is an example of one of the most popular
air resistance rowing machines on the market that have been adopted by many health clubs as well as rehabilitation centers and is the first pick for indoor rowing competition around the globe.
e.g., (i) degraded combustion, if any, (ii) momentum in the moving engine parts prior to the clutch plate, (iii) momentum due to the physical displacement of the vehicle, (iv) friction due to movement of the vehicle, of
which air resistance is one component, (v) dissipation of kinetic energy in the compression stroke, and (vi) braking.
The equation of the model can be modified to allow
for air resistance and the resulting equation can be solved numerically.
In reality, gravity and
air resistance drag and slow the droplets, causing them to follow curved trajectories.
Crash
Landing Air resistance typically slows stony meteorites to about 200 miles per hour, so they land with a relatively soft thud.
Galileo's work wasn't all staring at the sky, either: His studies of falling bodies showed that objects dropped at the same time will hit the ground at the same time,
barring air resistance — gravity doesn't depend on their size.
As the descending body penetrated deeper,
air resistance probably caused it to explode in an airburst with a strong flow of heated gas that was carried downward by its tremendous momentum.
The drag coefficient is coded into the game's software to
simulate air resistance, which greatly affects the pace at which an object rises and falls in the shape of a parabola.
«The ball moves at its fastest velocity when it comes right off the foot, and
air resistance immediately slows it down until it reaches its maximum height,» says John Eric Goff, Lynchburg College physicist and author of Gold Medal Physics: The Science of Sports.
Strange ball behavior in earlier versions of the game has been traced to an error in the
way air resistance was calculated
Developments in high - speed rail have historically been impeded by the difficulties in managing friction and air resistance [citation needed], both of which
The
maximal air resistance that this creates and the strong rear downforce increase the deceleration values from 1.4 G by an additional 0.6 G while maximising the braking stability.
The air suspension includes automatic load leveling to lower the truck at highway speeds for greater efficiency with
lessened air resistance.
Moreover, a 0.27 Cd of
