Essays on Air Resistance

 Why professional bicyclists have recently been descending hills at greater speeds.

Pedaling is a compound sport, which involves competitors, who must compete with a diversity of approaches, numerous environmental factors, and roughness on the ground. The operation on high grounds is an essential ascertaining victory factor in the leading international cycling tournaments. The main forces that a bicyclist must prevail over are; the gravity and air resistance. Air resistance rises exponentially with momentum. When pedaling from a smooth road to an ascending hill, the reduced speed lessens the air resistance to a level where leading other riders offers little benefit. Smaller bicyclists, who prefer to have a higher authority to ...

Ski jumping involves a lot of skill, and different factors affect how far the ski jumper would jump. Comprehending of the physics principles enable the skiers to execute certain moves. When these factors are manipulated in different scenarios, the desired distance is achieved. The sport of ski jumping requires one to jump the furthest down an inclined slope. It is done by gaining the maximum possible speed one can attain upon takeoff from the ramp. It is achieved by minimizing the frictional drag due to the air resistance between the air and the skier. The air resistance is significantly ...

Abstract

The aim of the experiment was to determine the relationship between the diameter of a steel ball and its terminal velocity in glycerol. Four balls with different diameters were put in a transparent cylinder full of glycerol. The velocity of the ball was calculated based on the time taken for the ball to pass from one mark on the cylinder to another. The results showed that an increase in the diameter of the steel ball leads to an increase in terminal velocity. Besides, the results show that the larger the diameter of the steel ball is, the faster the ...

Problem Statement - What are the accelerations produced by varying forces on a given mass? Hypothesis - If the force on a cart with a constant mass is decreased, then the acceleration will be greater

In this experiment Newton’s second law of linear motion was being investigated. A cart was connected by a ticker tape and a ticker timer used to get the velocity and time. The hypothesis was that a decrease of the force on a cart with a constant mass results in greater acceleration. This is because removal of certain masses results in an equivalent resultant force, hence more resultant force causes more ...
