A faster-moving object will have increased air resistance because more molecules of air will be encountered over the same time frame. The same holds true if an object that encounters denser air: there is more air resistance, therefore more lift as well as more drag.

∙ 12y agoAir resistance is a force that gets larger as an object moves faster.
Consider Einstein's equation E = mv2 and Newton that "for every reaction there must me an equal and opposite reaction." The latter is the law of Conservation of Energy. Resistance is a force, E, opposing another force in the opposite direction. V in the equation is velocity or speed. The opposing force in this case is the resistance of air and the reason why objects do not move forever except in space where there is no air.

By experimentation: air resistance = velocity 2 * objects drag coefficient

If there were no air resistance how did the speeds of a feather and a penny compare?
If there was no air resistance and a feather and a penny were dropped from the same height they would both pick up speed by the same amount and they would hit the ground at the same speed and at the same time.
What is the name given to fastest speed that anything can travel at because air resistance?
Terminal velocity.
What 3 factors affect the amount of air resistance acting on an object?
Speed, shape and frontal cross-section. Viscosity, texture, friction, gravity, velocity, size, and shape can all affect air resistance.
Air and water resistance?
Air resistance is that resistance when substance moves in air and it expresses a opposite force on it. However, water restinace is water when a substance moves thorugh water and it expresses and oppoisite force.
How are air resistance and friction alike?
Air resistance is a type of fluid friction (along with water resistance) and is therefore is a type of friction.
How does aerodynamics affect the speed of a car?
It changes the air resistance of the car - which is the controlling factor of top-speed.
What three factor affect the amount of air resistance on an object?
Speed, shape and frontal cross-section.
How does air resistance change speed?
Air resistance acts in the opposite direction of an object's motion to reduce its speed. The force of air resistance or drag is given by the following formula:FD = 1/2 A CD ρ v2whereA is the projected area of the objectCD is the drag coefficientρ is the air densityv2 is the relative velocity of the air
Do the velocity of falling objects does not change?
If there is no air resistance, they will fall faster and faster.If there is air resistance, they will eventually approach a "terminal velocity", a maximum speed, at which the downward pull of Earth is counteracted by the backward pull of air resistance.If there is no air resistance, they will fall faster and faster.If there is air resistance, they will eventually approach a "terminal velocity", a maximum speed, at which the downward pull of Earth is counteracted by the backward pull of air resistance.If there is no air resistance, they will fall faster and faster.If there is air resistance, they will eventually approach a "terminal velocity", a maximum speed, at which the downward pull of Earth is counteracted by the backward pull of air resistance.If there is no air resistance, they will fall faster and faster.If there is air resistance, they will eventually approach a "terminal velocity", a maximum speed, at which the downward pull of Earth is counteracted by the backward pull of air resistance.
How does air resistance change the longer an object falls?
The force the air resistance do against the object is proportional to it speed (F=C*v^2, usually, where C is a constant and v is the speed). So, the higher the speed, the higher the force. If an object is falling, the gravity is probably responsible for it. When the force of the gravity is equivalent to the force made by the air resistance, the speed of the object remains constant. To answer your question directly: without air resistance, the graphic position X time would be parabolic. With air resistance, it looks like an decaying exponential.
How does the force of air resistance depends on an object's speed?
In general the resistance increases by the 4th power of the speed.
What factors affect the speed of a falling object?
Factors that increase speed of a falling object:HEIGHT - The longer an object is in the air the more speed it gains due to gravityGRAVITY - The strength of the acelleration due to gravity (eg the moon is different to earth)STARTING VELOCITY - The speed the object starts at.Factors that decrease the speed of a falling object:AIR RESISTANCE - Air resistance is a major factor however it in itself is dependant on the air pressure around the object and the surface area of the object.
Why parachutists do not fall with constant accelerating motion?
Due to air resistance as the resistance is directly proportional to the speed but at certain speed called transitional speed or critical speed the resistance become directly proportional to square the speed so the resistance increase decreasing the falling speed.
The speed when falling objects no longer accelerates due to air resistance is?
The speed when falling objects no longer accelerates due to air resistance is the maximum falling velocity.
What features of an object will affect air resistance?
the amount of air resistance on an object depends on the size, shape, and speed of the object. Air resistance is the force that opposes the motion of objects through air.
How does air resistance affect the acceleration of falling objects?
As a falling object accelerates through air, its speed increases and air resistance increases. While gravity pulls the object down, we find that air resistance is trying to limit the object's speed. Air resistance reduces the acceleration of a falling object. It would accelerate faster if it was falling in a vacuum.
How does water or air resistance against an object increase speed?
It doesn't increase speed. The word resistance means to resist. In other words it decreases speed.
