1. OBJECTIVE The purpose of this lab was to use a motion sensor (photogates), computer software  application, projectile launcher, and time of flight pad to investigate what factors may  affect the time-of flight of a projectile. We would then use our graphical data produced  by the computer software to make comparisons between our data received by our time- of-flight experiment versus our horizontal velocity of a projectile experiment.  2. EQUIPMENTS Item Role Motion Sensors (Two  Photogates) Detects and records the motion of projectile object Data Studio Software  Application This software application charts, displays, and  scores the accuracy of each experiment. Projectile Launcher, with adjustable angle positioning Propelled the object (horizontal position = 0 ° ). Time of Flight Pad A flat sensored surface that measures the time  the projectile object reaches its final destination  Projectile A ping-pong ball Projectile Inserter Rod Helped push the projectile into the launcher Metric Ruler To measure distance away from launcher Stand Used to position the time-of-flight pad in a vertical  position PHY 2053 Lab Page 2 of 11 Unit 1

3. PROCEDURE The lab was divided in to two experiments.  The first, titled Time of Flight, required that we used the DataStudio file “13A Proj Motion  1” which recorded the average velocity of the projectile between the two photogates  mounted on the projectile launcher and the time-of-flight pad. We then had to place the  time of flight pad on the floor where we believed our projectile would land. The lab  required that we recorded data from three different ranges (long, medium, and short)  with the projectile launcher at a horizontal position of 0 ° , in addition to the same three  different ranges (long, medium, and short), but from an angled position of 30 ° . From the  horizontal position of 0 ° , we ran a few test runs to discover where our projectile was  going to land. We then used the DataStudio by pressing “start” on the time clock to

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
