Air Force Observation Essay

Improved Essays
Observations & Discussion
I observed that the results for the simulated launch of each object conducted without air resistance produced the same results as every other object. This was due to the fact that air resistance takes into account the mass and diameter of each object tested, so the results with this aspect differ greatly from one object to the next. I observed that when air resistance is considered, the lighter an object is or if its diameter is small, the object tends to travel farther than its heavier and wider counterparts. This is due to the forces acting on the object like gravity.
Uncertainty
I found that there was hardly any uncertainty in the results of the simulation without air resistance, however, the results of the test

What are the x and y components of acceleration when the projectile is in motion? Call y positive upwards.

The x component of acceleration is zero because projectiles have a constant velocity, resulting in no horizontal acceleration.
The y component of acceleration is a constant -9.8 m/s2 in relation to the gravitational force acting on the projectile.
Why does the x component of velocity remain constant?
The x component of velocity remains constant because since the horizontal acceleration is 0, then the x component of velocity (horizontal velocity) must be constant. The expression for horizontal velocity at any time is vx=c, and as you can see, there are no variables in the expression that change over time, so we can say that its value is always a constant.
Why does the y component of velocity change in time?
The y component of velocity changes in time due to the constant value of acceleration caused by gravity that is present on the projectile. The expression for vertical velocity at any time is vy=v0 (sin θ0)-gt, and as you can see, the value of the y component varies over time due to the fact that we must accommodate the presence of the time variable in accordance to

    1. How do you adjust the pulling force of the mousetrap? Adjusting the length of the snapper will change the pulling force—making something move as it goes in a certain direction. Making the snapper on the mousetrap longer will decrease the pulling force and a shorter snapper will increase it.…

    Trebuchets and Catapults Trebuchets and catapults have a significant impact in history. In the past, people such as the Arabs, Romans, and Greeks used them in war all the way up till the Medieval Era. In fact, these machines may have been major turning points towards winning certain wars. The creativity of people at that time ultimately made them the inventors of a new technology that would clear the way for more improvements. However, trebuchets and catapults were built for separate purposes.…

    My Slapshot In Hockey

    Last Thursday, I had a hockey practice, and before anyone else came on the ice, my brother Michael and I were just shooting around. To see how fast my slapshot is, I had him stand at the other end of the ice, and using his phone, see how long it took for my shot to go from one goal line to the other, exactly 60.96 meters. Keeping the puck on the ice the whole time during my shot, changing just the position of the puck, my slapshot took 4 seconds to cross the far goal line, making my slapshot move at a velocity of 15.24 meters per second. This calculation was done by divided the total displacement by the total time, 60.98 meters divided by 4 seconds. Finding the velocity of the puck relates to what we are doing in class, as we are talking about…

    1 University of the People Unit 5 Written Assignment Analyze the report and present a summary, in your own words, of the failures and your comments on them. A preliminary investigation of flight data showed: nominal behavior of the launcher up to H0 36 seconds; failure of the back-up Inertial Reference System followed immediately by failure of the active Inertial Reference System; swiveling into the extreme position of the nozzles of the two solid boosters and, slightly later, of the Vulcain engine, causing the launcher to veer abruptly; self- destruction of the launcher correctly triggered by rupture of the links between the solid boosters and the core stage. The origin of the failure was thus rapidly narrowed down to the flight control system…

    Record the height (Y_0) of the projectile and find the corresponding time of flight using the equation t=√(2Y_0)/9.8. Place the plastic ball into the launcher and use the push rod to load the ball until the “3rd click” is heard. Press the Start button on the Smart Timer and pull the launch cord. Record the horizontal distance (X) traveled by the projectile and the time from the Smart Timer. Repeat steps 2-4 five times.…

    The objective of this lab was to figure out how to determine the range from a given set of velocity and height from the ball. The height of the ball when it leaves the horizontal projectile is at 93.5cm or .935m. The velocity of the ball was .0674 seconds in the range of .1 meter. Creating a total velocity of 1.484m/s.…

    Unlike velocity, it is independent of the direction an object travels. Speed is only the magnitude (size) of the object (changes direction) . When velocity is the magnitude and direction the object will travel (doesn’t change direction). Velocity depends on another fact like in this case of a baseball would be air/atmospheric…

    1. How does the force of the Earth’s gravity 250 miles above the surface of the Earth compare to the force of gravity at the surface of the Earth? Is this surprising? The force of the Earth’s gravity 250 miles above has less pressure and less gravity because gravity pulls everything to the center of the Earth, so the farther the distance; the less gravity. The force of the Earth’s gravity 250 miles above the surface has about 90 percent of what the force of gravity is on Earth’s surface. For example, if a person weighed 100 pounds on Earth’s surface, and they climbed on a ladder all the way to the space station, they would weigh 90 pounds on the top of ladder.…

    When I made my initial assessment of this situation, I realized that this collision can be described by the principle of conservation of momentum. Despite the somewhat imposing name, this principle is actually quite intuitive in nature. To understand this principle, I utilize an example from my own life: duck hunting. While some may consider it a rather barbaric pastime, I rather enjoy the thrill of venturing into a marsh in the early hours of the morning and I love the satisfaction of dressing and cooking a prize. You know immediately when your shot is a successful one; a bird flying in one direction is suddenly and violently launched in another direction falling precipitously.…
