In a previous post, I was trying to show that the range of a projectile depends on the launch angle. Yes, this isn't that too difficult to see in an introductory physics course, but how do you show ...

I’ve started recreating many of my numerical model tutorials for introductory physics. In the beginning, I had students use spreadsheets to create models. Of course, spreadsheets aren’t very good for ...

We give a simple proof that the solution of the Allen-Cahn equation converges to Brakke's motion by mean curvature, by utilizing the recent results of Röger and Schätzle in space dimension 2 and 3.

Review with the class the method of finding the range and height of a projectile using projectile motion equations, as well as how to calculate the speed of an object by using the conservation of ...
