1-145-S-FastPitch
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...

4-036-S-AltitudeDependentGravity
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 inverse-square of the distance between the centers of mass of the Earth and the projectile. When projectiles are near to Earth's surface,...

4-039-S-FallingDarts
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...

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:...

3-091-S-MassSpringExperiments
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 spring-mass systems and solved second-order...

1-170-S-CensusModeling-StudentVersion
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...
