23 Jan 2022  Modeling Scenarios  Contributor(s):: Erich McAlister
Pitch velocity is one of the most fascinating statistics in baseball, as documented in the 2015 documentary Fastball. Modern measurements of pitch velocity are taken as the maximum velocity achieved at any point between the pitcher's hand and home plate. However, the velocity of the ball...

4036SAltitudeDependentGravity
22 Jan 2022  Modeling Scenarios  Contributor(s):: Jakob Kotas
Basic projectile motion without air resistance typically assumes gravity is constant. In reality, the acceleration due to gravity is proportional to the inversesquare of the distance between the centers of mass of the Earth and the projectile. When projectiles are near to Earth's surface,...

21 Jan 2022  Modeling Scenarios  Contributor(s):: Jacob Paul Duncan
Most projectile motion and free fall models are based on the assumption that gravity is the only force acting on the object. Here we develop, solve, and analyze a second order nonhomogeneous differential equation model for free fall which incorporates air resistance. Students will solve the model...

19 Jan 2022  Modeling Scenarios  Contributor(s):: Jennie D'Ambroise
This module guides students in the use of differential equation models to predict cancer growth and study treatment outcomes. Several classical models for cancer growth are presented including exponential, power law, Bertalanffy, logistic, and Gompertz. Students solve firstorder differential...

Potential Scenario Ideas : nuclear fusion for electric power generation?
17 Jan 2022  Potential Scenario Ideas  Contributor(s):: Andrew M Ross
It occurred to me that students thinking about climate change might want to take a look at electric power generation via nuclear fusion. I know very little about this area, but perhaps someone out there does? I think students would be interested in just about any of the proposed technologies:...

Potential Scenario Ideas : climate change: temperature, CO2, and some other factor in a feedback loop?
17 Jan 2022  Potential Scenario Ideas  Contributor(s):: Andrew M Ross
Looking at graphs of atmospheric CO2 and global average temperature, such as this famous one from "An Inconvenient Truth" https://smallpond.ca/jim/ref/inconvenientTruth/full/00_22_49.jpgor the 2nd graph on this...

17 Jan 2022  Modeling Scenarios  Contributor(s):: Jennie D'Ambroise
We describe a modeling activity for Calculus I students in which modeling with difference and differential equations is appropriate. This model enlightens students as to how derivatives are used in applications as well as a brief introductory encounter with parameter estimation for a linear,...

3091SMassSpringExperiments
14 Jan 2022  Modeling Scenarios  Contributor(s):: Bonnie Moon
In this lab students will collect data on their spring mass systems and compare their empirical models to their theoretical ones—giving them an opportunity to actually test a model against data. Before this lab, students should have modeled springmass systems and solved secondorder...

22 Dec 2021  Modeling Scenarios  Contributor(s):: Jean Marie Linhart, Gary William Epp
Students who have studied models for population are likely to be familiar with the exponential and the logistic population models. The goal here is to explore the role of modeling assumptions in choosing which model to use. We will compare and contrast the United States census data and the...
