How to Make a Linear Equation of Rubber Bands

By Society & Culture & Entertainment Last updated Friday, February/14/2025

1). Hold the rubber band to its full extent, lengthwise, without stretching it, and measure its length, with the ruler.
2). Stretch the rubber band for a predetermined amount of time. Experiment with time intervals of 2 seconds, 5 seconds, 10 seconds, and 30 seconds, and record the length of the rubber band after each period of stretching.
3). Input your time vs. length data into a graphing program, and determine the time intervals for which the graph of the rubber bands is linear. Eliminate all other points from the graph.
4). Use your graphing software to fit a best-fit line to the specific data points that fall into a linear pattern. This is the stretching time vs. length equation of your rubber band.
