Projectile Motion And Arrow Flight Essay

1316 words - 5 pages

An arrow whistles as it travels through the cool crisp air. Higher and higher it rises, up towards the heavens. It is soaring across the clear blue sky as it begins to fall. Gaining speed now, it is coming back to earth. What will be its fate?
An arrow is a good example of a projectile. A projectile is an object upon which the only force acting is gravity. It usually undergoes vertical motion as well as horizontal motion. The projectile, or in this case the arrow, is always being accelerated downwards. (What is a Projectile,1996-2001) As long as an arrow is traveling forwards it has a constant horizontal vector. Its vertical vector changes as it goes up and down. The horizontal vector stays constant because the projectile is still traveling in one direction. The vertical vector changes because the projectile is moving in one direction, up, and then in another, down. It can also have a constant vertical vector though. If a projectile were pushed off a cliff with no rising motion, then it would also have a constant vertical vector. (Motion, Energy, and Simple Machines, 1996)
So what is a vector anyway? A vector is the direction of motion that a projectile travels. It is made up of a magnitude and a direction. (Vector, 1991) There are two vectors, a vertical vector and a horizontal vector. They are not related. Horizontal and vertical vectors do not affect one another. The vectors play a part in the trajectory of projectile flight.
Vectors are not the only factors that play a part in projectile flight and trajectory. There are also velocities. The two kinds of velocity are vertical and horizontal. A velocity is the speed a projectile is traveling in a certain direction. The velocities are completely separate of one another. (Velocity, 1991) For example the speed of which a projectile is traveling horizontally does not affect the speed of which it is traveling vertically. In the same sense, the vertical velocity will not affect how far a projectile travels horizontally. A projectile usually has a constant horizontal velocity or speed, because an object in motion stays in motion, and there is no horizontal force. The vertical velocity does not remain constant because the speed at which a projectile travels increases as the projectile goes down. (Initial Velocity, 1996-2001)
Gravity plays a part in flight trajectory also, as well as in vertical velocity. Since
Gravity is always accelerating a projectile downward it is always gaining speed. The rate at which a projectile gains speed as it travels downwards is called the rate of gravity. The acceleration of gravity is always the same, and it is always 10/m/s or ten meters per second. It does not matter the size or the weight of the projectile it always falls at a rate of ten meters per second, but a part is also played by wind-resistance. Wind resistance may change may alter the speed a bit. For example, a smaller and less heavy projectile may be carried by the wind,...

The idea behind the fletching is to attach them to the shaft in a rotating motion so that when the arrow is in flight the air resistance created will actually rotate the arrow while in mid-flight, which stabilizes the arrow. The vanes and feathers are definitely a necessary evil, they may slow

No matter the form of the firearm, the same basic principles of physics and chemistry apply. The study of these principles is called ballistics. There are three types of ballistics, internal, external, and terminal. Internal ballistics is the study of the flight of a projectile inside a firearm. External ballistics is the study

One obvious problem for the Aristotelian view of forced motion was the behavior of projectiles, such as the flight of arrows. A force was only applied on the arrow at the start of the flight, but it kept moving through the air even after it left the bow, with no discernible forces acting upon it. Aristotle proposed that projectiles were kept in motion by the air displaced
