# Air Resistance Formula

As we have perceived, the air resistance decreases the speed of a planes that is moving in the sky.

Air resistance is a force that is initiated by air. This force acts in the conflicting direction to a body passing through the air. Air resistance exerts the frictional force of air against a moving body. As a body moves, air resistance decelerates it down. The quicker the body’s motion, the superior the air resistance applied against it. Air resistance impacts all moving objects, from bicycles, car, trains, and rockets to airplanes and even alive bodies. The resistance against the air is Air resistance, which reduces the speed of the moving body. Its formula is articulated as,

Where,

air constant is c,

the object’s velocity is v.

**Air Resistance Formula** is made use of in finding the air resistance, air constant and velocity of the body, if some of these numerics are known. This formula has wide applications in aeronautics.

**Air resistance Solved Samples**

Underneath are given some questions based on air resistance which will be useful to comprehend the concept.

**Problem 1: **A plane moving with a velocity of 50 ms^{-1} has a force constant of 0.05. Calculate its air resistance.

**Answer:**

Given: v (Velocity of air) = 50 ms^{-1},

c (Force constant) = 0.05

The force constant is given by F = cv^{2} = 0.05 × 2500 = 125 N.

**Problem 2: **An object is traveling at 20 ms^{-1} experiences a force of 50 N. Calculate the force constant.

**Answer:**

Given: Velocity of air v = 20 ms^{-1},

Force F = 50 N,

The force constant is given by
