Projectile Motion

Spring Surprise: Projectile Motion made Fun, Mathematical and Real!

Projectile motion often involves a lot of mathematical problem-solving that is overly simplified and highly contrived. Football players do not stop to calculate the range before making a pass. Invading armies might want to make calculations for siege weapons, but these tend to be too complicated (trebuchets) or involve too much energy loss (catapults). Guess and check, was probably the preferred technique. Fortunately there is a cheap and reliable projectile launcher that you can use to show that physics works. Your students will be able to use it to hit a target on their first shot by using calculations for conservation of energy and projectile motion. Read More...

GIFs in the Classroom

It’s autumn, and maybe you’re looking for a new way to impress your physics students this semester. I find it easy to amaze my class by using various forms of technology in my lessons. Often our students don’t realize how tech savvy physicists need to be, picturing us using chalkboards to give lectures and not using supercomputers at CERN or developing video games which use physics simulations. Ok maybe I’ve never been to CERN or made a video game, but I can make my own GIFs. In this article I’m going to show you some GIFs you can use in your lessons, and also teach you how to make your own GIFs. Read More...

Energy and Motion Connections in a K’Nex™ Catapult

It is very important to have our students engaged in the classroom in order for deep learning to occur. Your students need opportunities to use their creative spark and build on their 21st century learning skills. Peter Benson’s TED talk does a great job of presenting how important this is.

Ideas for projects proliferate but many of these are time-consuming, expensive and beyond the skills of an average student and the tools of an average physics classroom. However, your students can build a catapult with K’Nex™ in just one class with virtually no prep and no trips to the wood shop.

Water Rockets

Having students construct and launch a water rocket is an entertaining way to investigate Newton's Third Law of motion. Students can construct the rockets at home for an in-class launching session. Read More...
