Introduction
A Projectile is an object upon which the only force acting is gravity, and its continued
motion is influenced only by the downward force of gravity. Projectiles are commonly seen in
various aspects of our daily lives such as throwing a ball in sports or when a bullet is fired from a
gun. With this, in each direction the motion is either constant, or it is affected by gravity. Our
overall goal of this video analysis experiment was to visualize that a projectile motion has two
separate motions: horizontal and vertical or also known as x and y.
We were firstly asked to watch a video named Launch-45.mp4 where a launcher was set
up at a 45° angle and loaded in a plastic ball, where it goes through the air, and has three
different bounces before the video ends. Next we were asked to view the video
launch-45-data.mp4 where the scale was set for the video, and Video physics locates and
attempts to track its motion and data analyzed the initial launch, first bounce, and second bounce.
These data results were uploaded into an excel spreadsheet where there are three sections of data
for us to review the data tracked from the video. In this data sheet there are three sections: time,
X, and Y, where the time, measured in seconds, and the time in each row to the next is times
between the frames and video, along with the X and Y values. Based on the data given, we were
instructed to find the Y velocity of these data sets given, and create graphs using excel of
x-position vs. time and y-position vs. time. and for the y-velocity. We focused on analyzing the
movement of a bouncing ball by viewing the motion and tracking the ball's trajectory and
revealed the intricate relationship between these factors and how they affect the overall motion
of the projectile.The results of this experiment showed us that the ball gradually loses height due
to the loss of momentum with each bounce and that the acceleration of gravity is constant.
Data Collected
Throughout the lab, we collected data from the spreadsheet with launch data and ensured
we conceptually kept track of the values we should see in a launch like this. That includes the
ball’s trajectory, vectors, speed, velocity, and how gravity would apply in this lab, to the ball. We
developed the graphs below with the equations also that apply to acceleration of gravity (g). On
page 3, you can refer to three different graphs that refer to the x-position (m), y-position (m), and
y-velocity (m/s).
