## Does a larger surface area increase air resistance?

Table of Contents

The greater the surface area, the greater the number of air particles hit the object and the greater the overall resistance. There are two main things that affect air resistance- the speed of the object, and the cross-sectional area of the object.

**How does surface area affect air resistance?**

Most objects falling through air experience a type of friction called air resistance. Air resistance is not the same for all objects. The greater the surface area of the object the greater the air resistance.

**Is air resistance proportional to surface area?**

The drag force, or the resistance of a medium to the motion of objects in it, is proportional to the square of the velocity and to the Cross-sectional Area of the moving object. Decreasing the speed will therefore decrease air resistance and decreasing the surface area will decrease air resistance.

### How can you increase air 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.

**Does size affect air resistance?**

Air resistance, on the other hand, does not depend on mass, only on the density of air, the shape of the object, and the velocity of the object (or the square of the velocity, depending on the size and density– air resistance is messy…).

**Why does larger surface area increase drag?**

The total aerodynamic force is equal to the pressure times the surface area around the body. Drag is the component of this force along the flight direction. Like the other aerodynamic force, lift, the drag is directly proportional to the area of the object. Doubling the area doubles the drag.

#### How does cross sectional area affect air resistance?

Air resistance is the result of an object plowing through a layer of air and colliding with air molecules. 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.

**How does surface area affect terminal velocity?**

The position in which the object falls changes the surface area and in turn changes the terminal velocity. If the object has a greater surface area it will have more room for air resistance to work on it. There will be a greater upward force and a smaller terminal velocity.
