Abstract

Resource Image We guide students through the development of an empirical model for the velocity and distance traveled of a simple pull-back toy. Students can record videos and extract data using their own pull-back toy or use data included.

Description

This hands-on modeling scenario guides students through the development of an empirical model for the velocity and distance traveled of a simple pull-back toy. Students can record videos and extract data using their own pull-back toy or use data included in the student version.

Two different models are proposed for the torque delivered by the pull-back motor and students will use the experimental data to determine which model is more accurate while also predicting the top speed and maximum travel distance of the toy.

An optional theoretical component justifies the form of the second-order differential equation used in the mathematical model.
