Projectile Motion Lab

Introduction: The purpose of this experiment was to find how changing the angle and velocity would affect the distance the object went, height the object went, and time the object was in the air. Before this lab I could not tell how the angle and velocity would change the results. I needed to figure out what angle and what velocity made the object go farther or make it stay in the air longer. I also found mass will affect the height and distance. I used the site Galileo and Einstein to figure out these factors. (Fowler, M)

Theory: The theory behind projectile motion is anything thrown or shot moves at a constant speed and is affected by a constant acceleration of -9.8 m/s2. (Projectile Motion) The equation x = vot shows the distance the object will travel (Physics: Principles and Problems). The equation v = vo+ at is used to measure the height. To get the total velocity we add both velocities.

Experimental Procedure: First open internet explorer and visit http://galileoandeinstein.physics.virginia.edu/. When the page is opened click on Applets, on that page click on Projectile Motion. I used this to adjust the projectiles angle and velocity which would determine the distance, time or height of the object. Changing the variables was not hard; however you had to make sure it met the requirements and did not exceed the limit that was given. After I got all my results and data I had to get on to a school computer to access the “Data Studio” software. After on the software, we had to click “Graph Equation”. Then after given the chart I entered my data which created a graph. After reassuring the data was correct we added labels such as meters or seconds. After everything was correct we had to click “Fit” to make a best fit line. There were many options but majority of the lines were either a “quadratic” or “line” depending on the graph. Once the best fit line was placed the graph was complete. This was done six times for each set of data to make six separate graphs. All six graphs were printed.

    For each test, I was required to calculate the height of the pendulum required in order for it to have the same mass, or the quantity of matter affected by the external force of gravity, as my project. To find the height, it required understanding the process of the pendulum hitting my project step by step. As the pendulum is pulled back, it has its maximum potential energy, which is the energy possessed by a body by virtue of its position relative to other objects. When the pendulum is let go, it loses potential energy while gaining kinetic energy, or the energy that a body possesses by virtue of being in motion. At the bottom of the swing, kinetic energy of pendulum is the greatest because the change in potential energy equals the kinetic energy at the bottom of the swing. As the pendulum hits my project, there is an impulse, a force acting briefly on a body and producing a finite change of momentum, between the pendulum and project. As the pendulum hits my project, the project carries the momentum of the pendulum with it. By working in reverse order, the height of the pendulum required was

    I hypothesize that if I build the ratapult to a 25-degree angle, and release the hacky sack at a height of .55m then there will be enough velocity to project the hacky sack exactly four meters. The ratapult will release the hacky sack with an initial velocity of 5.8 m/s, and as a result the hacky sack will travel 4.0 meters in .75 seconds.

  • Projectile Lab Essay

    The purpose of the projectile lab is to test the validity of the law of conservation of energy. The application of this law to our everyday lives is a surprisingly complicated process. Conservation of energy states that energy cannot be created or destroyed, but that it can be transferred from one form to another. Consider the projectile lab from document A that this essay is based upon. In an ideal experiment, the projectile is isolated from everything except the gravitational field. In this case, the only force acting on the particle is gravity and there are only two forms of energy that are of interest: the energy of the particle due to its motion (defined as kinetic

  • Physics of Rifle Recoil

    1157 Words  | 3 Pages

    When the gun is fired, the bullet is projected forward by a force, and an opposite force (F) pushes backward on the gun. Since the barrel where the force is acting is slightly above the point of contact with the shooter's shoulder, torque is created. The normal forces put on the gun by the shooter's hands momentarily become negligible.* The forces acting on the gun directly after the gun is fired can be simplified as in Figure 3. R is the perpendicular distance between the recoil force and the point P. L is the perpendicular distance between the location of the force due to gravity and the point P. The resulting linear and angular acceleration can be seen in Figure 4.

  • Using Parallax and its Formula to Measure Distances: Science Project

    558 Words  | 2 Pages

    As my science fair topic, I chose to test the accuracy of using parallax to measure distance. I chose this topic because it relates to two of my favorite topics: mathematics and astronomy. Parallax uses a mathematical formula and is most commonly used to measure the distance between celestial bodies. From my research on parallax, I found how to measure it, and how to use the parallax formula to measure distances.

    Ancient mangonel catapult had the maximum range of approximately 1300 feet. Correspondingly, our mangonel catapult will be one-fourteenth the size of that used by ancient Greeks and Romans, therefore it will likely exert a maximum range of about 93 feet, or one-fourth the length of a standard football field. In order to measure the maximum distance in comparison to the height of the desired target, we will adjust the angle of the catapult, which will act as our independent variable, or the variable that we will change. We hypothesized that at a 45 degree angle, the catapult will exert its maximum range and successfully strike the target. The perception of this hypothesis derives from the basis of vectors and projectiles. For example, if we were to take three different launch angles, 30 degrees, 45 degrees, and 60 degrees, then the 60 degrees angle will achieve the peak height because it has the greatest vertical velocity, the 30 degrees angle will reach the ground the fastest because it has the smallest vertical velocity, and 45 degrees angle will achieve the greatest range because the vertical and horizontal velocities are the same, meaning that the time of the flight is coupled with the

    The definition of a projectile is an object that the only force acting on it is gravity. Projectile motion is the path the projectile takes. We saw and used this topic a few times in our project. The first time we saw it was when the marble was flew out of the pipe and was in the air. The second time we used the topic to make sure the trains fell on the lever in the correct spot so the golf ball would roll. The third time it was used, was when the board fall on the balloon. It fell as half of a parabola since it started standing up.

  • Physics of Firearms

    A firearm, in the most basic form, consists of a barrel, an action, a firing mechanism, a stock and a sighting device. 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 of the flight of a bullet after leaving the muzzle and until it hits the target. Terminal ballistics is the study of the effects of a projectile on a given target. Because this essay deals with the flight of the bullet, terminal ballistics will not be discussed.
