A Simple Mechanical Experiment on Exponential Growth
McGrew, Ralph
Physics Teacher, v53 n4 p222-223 Apr 2015
With a rod, cord, pulleys, and slotted masses, students can observe and graph exponential growth in the cord tension over a factor of increase as large as several hundred. This experiment is adaptable for use either in algebra-based or calculus-based physics courses, fitting naturally with the study of sliding friction. Significant parts of the activity are accessible to students in physical science and environmental science courses.
