The Charging Rhinoceros



When teaching introductory physics to non-specialists, I always try to use examples from subjects that might interest them. In my Physics 1007 course, which is algebra based, I I have many biology and neuroscience students, so I try to find examples from the natural world.

To make kinematics more interesting, I use an example of the cheetah in my lectures, and usually use other animals in tests or exams. The charging rhino problem is an old exam problem.

This was recorded using Microsoft Whiteboard, using my laptop's inbuilt microphone, and using a rather spiffy new Wacom Intuos graphics tablet, which I am still learning how to use. Occasionally I trigger a hypersensitive mode, which draws on the screen, even though the pen isn't in contact with the tablet surface, and a couple of times, I have triggered the zoom in or out of the screen view mode too. Fortunately I have been able to do a little bit of editing, and hopefully, the rough edged don't show too much. The other thing that I didn't realize, until I was doing the editing, is that the Xbox capture software doesn't capture everything on screen. At one point in the problem, I put the Windows calculator up to work out the final displacement, and it does not show up on the video capture. On balance, this could be an advantage.


Anyhow, for your delectation and delight, here is the final narrated product:
