Bungee Jump Lab Report

Introduction Gravity is a natural force that is the result of various distributions of matter and energy throughout the universe. All objects have gravitational pulls but as an object becomes more massive, its gravitational pull increases and takes precedence over the gravitational pulls of other smaller objects as demonstrated by the solar system in which Earth resides. Earth’s moon rotates around Earth due to Earth’s gravitational pull while Earth rotates around the sun due to the sun’s gravitational pull. Note how the less massive bodies orbit the more massive bodies due to that uneven distribution of mass and energy in the universe. The generally used equation for gravity as developed by Sir Isaac Newton is as follows: With F equalling …show more content…
Equipment used in this experiment in addition to the materials used for the bungee jump apparatus included Vernier LabPro, connected to the Dual Range Force sensor and the Ultrasonic Motion Detector, and Logger Pro. The Dual Range Force sensor was used for measuring the force, given in Newtons, of the bungee jump either pulling or pushing on the attached hook. The Ultrasonic Motion Detector provided information on the change in the bungee jump’s position by measuring its distance from the sensor. These sensors provided invaluable information for providing relationships between position, velocity, acceleration, and force as functions of time. While the Vernier LabPro device transmitted measured data onto the computer, Logger Pro would simultaneously generate graphs for …show more content…
Using the data we collected in Logger Pro we created position-time graphs and velocity-time graphs. We found that the average acceleration for the falling weight according to our collected data was -4.084 m/s2. The velocity-time freefall equation for the weight would then be y = -8.007x + 3.012. This equation makes sense because we found that the time frame during which the weight was in freefall was t=0.38 s to t=0.83 s, which means that the weight was in freefall for a little under .5 s. This lines up with our slope and y-intercept in our equation because it would take slightly under a .5 movement on the x (time) scale in order for our velocity-time freefall equation to intercept the x-axis. This means that according to the graphical representation, the weight is no longer in freefall after a little under .5 s which parallels our collected
