Air resistance can be decreased by making the object more aerodynamic, such as by reducing its size or shaping it to minimize drag. Smooth surfaces and streamlined designs help to reduce turbulence and resistance. Additionally, reducing the object's speed can also decrease air resistance.

What is the disadvantage of air resistance?
Air resistance can slow down moving objects, leading to decreased speed and increased energy consumption. It can also cause objects to lose altitude or stability, making it more difficult to control their movement. Additionally, air resistance generates heat, which can be detrimental to the object or its surroundings.
How does air resistance effect sports?
Air resistance (also known as drag) can slow down objects moving through the air, affecting their speed and trajectory. In sports, it can impact performance by increasing the amount of energy needed to overcome resistance, leading to decreased speeds and distances. Athletes often work on optimizing their technique and equipment to reduce the effects of air resistance to improve their performance.
How can water resistance and air resistance be reduced?
air resistance can be reduced by making the object that takes the air resistance stremlined. this means to make the object into a certain shape that alowes air to flow over the same is done in water but with a different shape
Why does decreasing the surface area of a piece of paper decrease its air resistance when it is dropped in the air?
Decreasing the surface area of a piece of paper reduces the drag force acting on it as it falls through the air. This is because there is less area for air molecules to interact with the paper, resulting in lower air resistance. As a result, the paper falls faster with less air resistance when its surface area is decreased.
Why does a balloon fall off a wall quicker on a hot humid day?
On a hot humid day, the air is less dense, which means there is less air resistance acting on the balloon as it falls off the wall. This decreased air resistance allows the balloon to fall more quickly compared to a cooler, less humid day.
How can resistance be decreased?
Aerate the water: pump lots of small air bubbles into it.
What happens to the power of an electric circuit of the resistance is decreased?
if the resistance is decreased and the current stays the same, then the power decreases.

Does air temperature affect air resistance?
There are two factors that influence air resistance with temperature. Air density decreases with temperature so that the force needed to push the air out of the way is decreased, thereby decreasing resistance. Conversely, air viscosity increases with temperature (unlike oil for example where viscosity decreases with temperature) so that the drag increases. Under normal conditions, the density change of air has the greatest effect and air resistance decreases at higher temperatures.

Which Air Pollutant Decreased The Most From 1970 To 1991?
"lead" is the air pollutant that decreased most in 1970 to 1991.
What does acetylcholine do to bronchioles?
Acetylcholine causes bronchoconstriction by binding to muscarinic receptors on smooth muscle in the bronchioles, leading to narrowing of the airways. This can result in difficulty breathing and decreased airflow to the lungs.
What is air resistance and what are the two factors that air resistance depends on?
Air resistance is the force that opposes the motion of an object through the air. It depends on the speed of the object and its surface area exposed to the air.
What force slows objects moving through the air?
Air resistance
