Projectile Motion In Archery Essay

1191 words - 5 pages

Archery, a sport that dates back to centuries before today, has been modernized to become more efficient and high tech. The Egyptian made the first complex bow in 2800 BC. The bow was made from sheep intestines and the arrow was light and efficient enough to be shot from 400 yards away and still penetrate the armor used at that time. Archery was a skill set that was prized in the military, especially in Rome. However, in 16th century a new tide was turning in Europe, firearms were slowly replacing the bow and arrow as military weapons. Other parts of the world were not as fast to leave behind archery this weapon. The people of the Far East employed archery in warfare until the 19th century, ...view middle of the document...

* The aspects of projectile motion I will be exploring are velocity, angles, gravity, distance, and height.
Projectile Motion
Projectile motion is the act of any object moving through the air or space, acted on only by gravity and air resistance1, if there is any. In the case of archery, it is the act of the arrow being released, flying over x distance, and landing at any given point due to the push of gravity. Projectile motion often occurs in the shape of a concave down parabola. The shape of this parabola depends on the projectile angle of the arrow. The draw force of the bow will determine the velocity at which the arrow will be launched.
Velocity
The mass of the arrow used in the table2 below is 00.0282 kg

This table shows how much work is put into the compound bow and conventional longbow via draw force. Since Work= Force∗Distance, the answers in the last two columns are obtained by the formula Flbs ∗ ((dfn-1-dfn)/12). Flbs being the pounds force and df, the distance from full draw. Following this formula I calculated the launch distance. For the compound bow, I did 10∗((0.5-0.0)/12), getting approximately 0.42.
To get the velocity I got the individual sums of the last two columns in the table, 73 foot-pounds for the compound bow, and 50 foot-pounds for the conventional longbow. I then multiplied my answer by 1.356, converting my answers into Newton meters. My answers were 98.9 Nm and 67.8 Nm. I then applied the formula in order to obtain the velocity. The mass in this equation would be that of the arrow, so the equations for the velocities of the two bows, once written out, would look like and , yielding 83.8m/s for the compound bow and 69.3m/s for the conventional longbow.

Angles
Hitting the target is always the goal in archery; however, this requires the arrow to be launched from an angle (. I wanted to see if the arrows being launched at different angles would eventually show which bow would have it arrow cover more distance. In projectile motion, the horizontal and vertical velocities are independent to one another. Thus, you have Vx=V*cos(θ), the horizontal velocity and Vy=V*sin(θ), the vertical velocity

The projectile connects the two rails together creating what is called Lorentz force. The result is an electromagnetic force that sets the projectile in motion at speeds of up to 5,600mph. The amount of power applied along with the size of the projectile help determine how far and fast the projectile will travel. The current aim for the Navy is an

Although physics is understood to be only useful in the classroom, physics can also be applied to one the most popular activities on the planet, basketball. Whether jumping for the ball, or leaping for a slam dunk, the human body follows the same laws of projectile motion as do other objects. The sport

Projectiles were placed in the pouch and flung through the air up to eight hundred yards. The long end was tied to a base that kept it from being thrown into the air by the counterweight. Once this rope was severed, the projectile went into motion. Possible projectiles of the trebuchet were living prisoners, jugs of Greek fire, rocks, and

From Aristotle to Newton: The Development of Modern Physics

1869 words - 7 pages . Galileo argued that objects retained their velocity unless acted upon by a force, such as friction. Therefore, an object that was set in motion would continue in the direction of its motion unless acted upon by an outside force, a concept that Newton later would use in forming his laws of motion. From this experiment, Galileo developed the concept of inertia, which was quite contrary to Aristotle’s ideas of motion. He stated that a projectile

In the same sense, the vertical velocity will not affect how far a projectile travels horizontally.

The vertical velocity does not remain constant because the speed at
