the study of aerodynamics and gravity

My topic for the science fair is “ Which falling objects fall the fastest? “. Many factors affect the speed of aerodynamics such as the different forces on the object. The aerodynamics of the object and the physics surrounding the object. Great scientists have studied falling objects such as Galileo Galilei and Sir Isaac Newton. I will discuss their lives, experiments and scientific findings.

Aerodynamics is the study of force on an object. It has been called the science of flight. Aerodynamics consists of two Greek words. Aerios means “ concerning the air “, while dynamis means “ powerful “. The wind duct is the basic experimental tool in the studies of dynamics. The three main forces used in aerodynamics are the lifting force, the drag force, and the weight force. Aerodynamics is technically the science that was used to develop flying machines, such as helicopters, airplanes, jets, and rockets. Aerodynamics principles are primarily concerning flight. However, aerodynamics principles are used in designing automobiles and train bodies. Since aerodynamics also studies gases in the air, aerodynamics help determine frictional events in gas ducts and it also helps chart the flows of the pollutants in the air. It has been found that people have been interested in aerodynamics for thousands of years. Aerodynamics not only involves the motion of the object(s), but also the reaction of air to the object. When aerodynamics has plenty of rolling components, you then will see friction. Friction is a force that resists the relative motion or tendency to such motion of two bodies in contact.

Physics is the study of matter and energy and their reactions. The word physics comes from four main languages. Although strange, these four languages all pronounce physics the same way or they are very close. These four languages are Old French, Greek, Latin, and Middle English. Middle English is the English language from 1100 to 1500. Isaac Newton was the person who experimented with many areas of physics, but it was Galileo Galilei who discovered that all items fall at the same speed without air. Newton discovered that forces do not cause motion; they cause acceleration. Newton also discovered that a force is not needed to keep an object in motion. Newton conducted several experiments. His most famous experiment happened in his backyard. He was sitting under an apple tree re...

... car will not hit a terminal velocity. Thus, it will hit the ground first. But, there is only air resistance inside of atmospheres. In plain space, there is no air resistance. If you jumped, you would float up, up, and away. People spend their lives trying to figure out more about air and air resistance. There was tons of stuff on Google, trust me! These people found out that the thickness of the air changes the amount of air resistance there is. Drag force, which is the force that tries to drag you up, is weaker than gravity. The drag force plays a crucial role in all speed-related sports. The drag force is the most important factor in swimming. The drag force affects vertical motion too. The drag force affects skydivers with parachutes. The wind fills the parachutes and slows the skydivers down.

In conclusion, there are many types of forces that are used in free falling such as, air resistance, gravity, terminal velocity, the drag force, and other frictional forces. There is so much information on free falling and I have barely made a dent in it. If you would like to find out more information about air resistance, free falling, or any other forces, just check my bibliography.
