What is another word for air?

Here are some adjectives for air: horizontal misty, palpable brown, breath-real, deep breath-real, stale warm, nitrous and common, serious contemplative, fresh nitrous, grateful fresh, ever-present enchanting, dry pure, deep and sleepy, keen pure, pure frosty, open and fresh, properly thick and fragrant, properly thick …

Here on Earth, we tend to take air resistance (aka. “drag”) for granted.

Air resistance is a type of friction between air and another material. For example, when an aeroplane flies through the air, air particles hit the aeroplane making it more difficult for it to move through the air. It’s the same for an object moving through water.

What is another word for resistance?

The greater the cross-sectional area of an object, the greater the amount of air resistance it encounters since it collides with more air molecules. When a falling object has a large mass, it weighs more and will encounter a greater downward force of gravity.

Also known as ‘drag,’ air resistance is a force caused by air. The air particles hit the front of an object, causing it to slow down. The greater the surface area, the greater the number of air particles hit the object and the greater the overall resistance.

Air resistance depends on velocity, area, and shape of the object going through the air. Altitude, temperature, and humidity change air density and, consequently, its resistance. The higher the speed and the bigger the area, the higher the resistance.

Friction is a force, the resistance of motion when one object rubs against another. Air resistance occurs between the surface of a falling object and the air that surrounds it and it also works to slow the rate at which the object falls.

Friction can slow things down and stop stationary things from moving. In a frictionless world, more objects would be sliding about, clothes and shoes would be difficult to keep on and it would be very difficult for people or cars to get moving or change direction.

Air friction acts between the object and the air through which it is moving. It is also called drag. This force depends upon the object’s shape, material, speed with which it is moving and the viscosity of the fluid. Viscosity is the measure of the resistance of the air to flow and it differs from one density another.

The third force, which factors into wind’s speed and direction is friction. Even though air is a fluid, the air molecules still rub across the surface of the Earth. Air is also channeled and diverted by buildings, trees, and hills. All these effects cause friction, a rubbing of the air molecules across the surface.

Friction manifests as heat energy generally and sometimes as noise. When objects are moving against each other, there is a generation of kinetic energy. Friction causes this kinetic energy to change into thermal energy. The biggest disadvantage of friction is wear and tear that happens as a result of friction.

Static friction can be stronger than kinetic because weak chemical bonds occur between atoms of stationary surfaces. The direction of the frictional force is always opposite to the direction of motion or attempted motion. Air resistance increases with increasing speed.

Even in gases there are circumstances where the frictional resistance is approximately proportional to the velocity – such as the motion of tiny dust particles through the air. More commonly, air friction has terms proportional to the square or even higher powers of the velocity.

When an object (say a boat) moves through water, there certainly is a type of friction. The layer of water near the boat at least partly moves along with the boat, and rubs against other parts of the water. This friction in liquids is different from friction between solids in an important way.

Friction is a resistive force, which comes into play when there is a relative motion between two bodies in contact. The frictional force between two bodies depends mainly on three factors: (I) the adhesion between body surfaces (ii) roughness of the surface (iii) deformation of bodies.

Greater speed causes greater air resistance, and increased area increases air resistance as well. It also depends on an object’s shape. When a plane drops from a high altitude to a lower one, it naturally speeds up just like anything that is dropped.

If there is no air resistance, after you let go of an object the only force on it is the gravitational force. More massive objects have a greater gravitational force. The acceleration of an object is proportional to the net force on the object and inversely proportional to the mass of the object.

Air resistance is the outcome of collisions between the object’s leading surface and air molecules. How much air resistance the object encounters depends on the speed the object is traveling and the cross sectional area of the object. When the object is falling faster, this increases air resistance.

You might think this is because the air resistance force depends on the mass, but you’d be wrong– it’s exactly the opposite. Air resistance is insignificant for heavy objects precisely because it doesn’t depend on the mass. Specifically, the change in motion due to air resistance gets bigger as the mass gets smaller.

heavy objects will have a higher terminal velocity than light objects. It takes a larger air resistance force to equal the weight of a heavier object. A larger air resistance force requires more speed.) Therefore, heavy objects will fall faster in air than light objects.

Resistance doesn’t depend upon mass . Resistance is directly proportional to lengths .. so their Resistance ratio will be 5:3:1 ..

Two ways to reduce air resistance are stated: reducing the area in contact with air (by the cyclist ducking down or cycling behind someone else) and by being more streamlined (wearing smoother surfaces or a more streamlined helmet).

Free fall occurs for falling objects that are only under the influence of gravity. During free fall, other forces such as air resistance do not affect the object’s movement. The object is falling at constant velocity so there is no change in direction or speed, which also means no acceleration.

Air resistance—Air resistance is the force on an object moving through air. Air resistance affects how fast or slowly objects move through the air. Water resistance – Water resistance is the force on objects floating on or moving in water.
