Introduction: The purpose of this experiment is to study the motion of an object in free fall, and describe this motion mathematically. The motion of an object is well known to be described by constant acceleration, as long air resistance can be neglected. In this experiment, we analyzed the motion of an object in free fall as if we did not already know this result. We are able to conclude from our analysis that such objects do fall with constant acceleration. We also are able to determine the magnitude of that acceleration. Experimental Technique: We used a device called the “Behr Free Fall Apparatus” to record the motion of an object in free fall. An object with a conducting metal ring is dropped between two vertical copper wires, connected to a high voltage power supply. As the object falls, sparks jump from one wire to the metal ring, and then to the other wire. Each spark melts

### What students are saying

• 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.
