For the past few years, students in my first semester calculus physics laboratory have explored kinematics (and also a little dynamics) by building and launching model rockets. Working in groups, the students build Estes Big Bertha or Baby Bertha rockets from kits. Then, we travel to a local park to launch the rockets. The rockets

In order to run the following simulations you need a web browser capable of running javascript and of interpreting HTML5. Brownian Particle Simulation in 2D A Simulated Time-Lapse Video of Brownian Particles in 2D

In Excel, you can apply a line-of-best fit to any scatterplot. The equation for the fit can be displayed but the standard error of the slope and y-intercept are not give. To find these statistics, use the LINEST function instead. The LINEST function performs linear regression calculations and is an array function, which means that
