One of the standard parts of an introductory physics course is a study of Newton’s Three Laws of Motion. They are part of the Ontario curriculum for grade 11 physics and most teachers would agree that they are essential. Chris Meyer has presented an improved way to teach the three laws of motion that will deepen student understanding: Teaching Forces I
and Teaching Forces II
In this article, I hope to reinforce Chris’ approach with a look at how the history of these three laws is wrongly presented. Read More...

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...

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...

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. Read More...

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...

This is a very popular game I have played with my OAC physics class. It incorporates the concepts of conservation of energy and projectile motion. Read More...
