Title
Projectile Motion
Abstract
A projectile was fired from atop an elevation and an angle. The initial velocity for each firing was likely to be the same. The distance traveled in the horizontal direction was measured for multiple firings of each trial, and the values were averaged. When the initial velocity for each of these averages was calculated it was proved that the initial velocity was relatively constant. These measurements had many possible sources of error including air resistance and firing position. This lab increased understanding of projectile motion.
Introduction
Projectile motion occurs when an object in a two dimensional plane experiences motion only due to gravity. Kinematic equations can be used to describe the components of projectile motion. This allows us to analyze the motion. In this lab measurements will be taken to determine the initial velocity of objects experiencing projectile motion. This will first be done for objects that are starting from a set elevation above the landing area. Then the initial velocity will be found for objects that are launched from the floor at an angle to a landing area of the same elevation. This will teach the concepts of projectile motion for objects that start from horizontal and objects that start at angles. Familiarity with kinematic equations will be increased through there repeated use in this lab. Also, this lab will create an understanding between the measure of the initial angle, and the distance a projectile travels in the x direction. Because the same instrument will be used to fire the projectile each time, and the projectile used will be constant, the initial velocity will likely be the same for all situations tested.

Methods
The pendulum of a ballistic pendulum was moved back so that it would not get in the way of the firing mechanism. This became the instrument that would be used to fire the projectile for this lab. This was initially place on a

For the example of a ball being thrown up into the sky and then landing on the ground, we can model a quadratic equation to show the path of the projectile at various points in time (projectile motion). That is to say, each point plotted on the graph (parabola) will be a measurement to this effect:…

You have learned that the motion of any object moving through the air affected only by gravity is an example of projectile motion. Examples of projectile motion include a basketball thrown toward a hoop, a car driven off a cliff by a stunt person, and a marble launched from the CPO marble launcher. Toss a ball some distance and you can imagine in your mind the arc it follows, first rising then falling to the ground. Projectile motion is also called two-dimensional motion because it depends on two components: vertical and horizontal. The range is the horizontal distance that the projectile travels between launch and landing. In this experiment, you will see how the range is related to the launch angle and initial velocity of launch.…

We used carbon paper on top of white paper to determine where the ball lands on the floor. We then shot the ball at angles of 30, 35, 40, 45, and 50 degrees. We recorded the distances after each shot and determined that shooting the ball at 40 degrees gave us the maximum range. We kept the launcher at a medium setting and shot the ball straight out 5 times and determined what the average range was at this degree. We used that data to determine that the initial velocity was 4.627 m/s. Next we chose our own angle which was 22 degrees and predicted that the range would be 2.57 meters. We then shot the ball 5 times and determined the average range of flight was 3.03…

The two pictures below demonstrate the calculations from Trial 1 at 0° and Trial 1 at 45°. In this experiment we did five separate shots from the cannon at 0°, and 3 separate shots at 45°. We determined the average distance of the shots from each angle by using a meter stick. We were then able to calculate the velocity of the shots by dividing the time from distance. After getting the results, the distance from the shots fired at 45° had a greater distance from the shots fired at 0° horizontally. This is because as the ball which is fired increases, the height increases. As the height increases, the time it takes for the ball to hit the ground increases and the range (distance) is greater.…

Kinematics is the study of the motion of bodies without reference to mass or force. This lab aided students in observing kinematics by giving them a visual graph to look at from experiments previously performed. Variables used in this lab were “x” for position of the object, “v” for velocity of the object, and “a” for acceleration of the object. Understanding the graphical representation of motion was important in helping students understand how position, velocity, and acceleration are affected with a moving object over a certain period of time. Using a motion detector and an Xplorer GLX, a calculator that graphed our distance velocity, and acceleration, students were able to create graphs for the information. The purpose of this lab was to allow students to visualize a graphical representation of the physics of kinematics being preformed.…

Projectile motion can be split into two separate dimensions of movement. The first being constant motion in the horizontal x axis witch neglecting air resistance should stay constant throughout the projectiles path. In the vertical y axis we have constant acceleration due to gravity toward the ground. These two motions are linked in time witch allows you observe the instantaneous characteristics of the projectile. Time is the connecter between the equations so you can salve for time in one equation and plug it into the other to find the data needed at that time/distance. Let's start by analyzing the horizontal x axis. Often the distance traveled by a projectile in the horizontal is called range(R = VicosÓ¨Ît). When broken down Vi cosÓ¨Ît is the initial velocity of the object in the x axis multiplied by how long it has been traveling at that speed equals your displacement in the x axis. The other dimension is the vertical witch is usually called height (h=VisinÓ¨Ît+1/2at^2) witch is similar to the horizontal motion except we have to account for the force of gravity. When we brake down the equation we see the height is equal to the initial velocity (VisinÓ¨Ît) of the object in the y axis plus half the force of gravity multiplied by the amount of time in the air squared witch yields the displacement in the y axis. Both equations are needed to represent the projectiles overall motion and can be manipulated though algebra to figure out the different components of…
