## Teacher Resources

The Physics Classroom has been devoted to helping students, teachers, and classrooms since the 1990s. We are as passionate about that mission now as we have ever been. If you are a teacher of Physics or Physical Science, we encourage you to use our Video Tutorial with your students. And we also encourage you to consider the use of other resources on our website that coordinate with the video. We have listed a few below to help you get started.

Curriculum Corner: Momentum and Collisions

Get students active and thinking with one of our free Think Sheets from the Curriclum Corner section of our website. Either of the following would make a perfect follow-up to this video tutorial:

Action-Reaction and Momentum Conservation

Collision Analysis

Our Concept Builder program may be the very thing your students need to solidify their learning. When combined with our Task Tracker program, it makes an excellent and cost effective homework-tracking tool. This particular one provides info about the post-explosion speeds of two carts involved in an explosion. Students must identify which one(s) violates the law of momentum conservation. Great critical thinking!

Here's another Concept Builder to strengthen conceptual understanding of momentum conservation. It is similar to the above Concept Builder except the analyses will involve hit-and-stick collisions instead of explosions. Great thinking!

This Concept Builder will challenge students to use the law of momentum conservation to complete a momentum table for a hit-and-stick collision. It's a great pre-cursor to the solving of Physics word problems. Awesome practice!

This Concept Builder is similar to the above except that it involves Hit and Bounce Collisions. More awesome practice!

Physics Interactives; Collision Carts

Our Physics Interactives section includes numerous simulations in which students play with variables and observe the result. This is one of our most popular sims. Best of all, it comes with classroom-ready, printable activity sheets.

Physics Interactives; Exploding Carts

This simulation is similar to the above but it's all about explosions instead of collisions. Students alter the mass of one of the objects and observe the effect upon the post-explosion velocities of the two cars. It is accompanied by a ready-to-use activity sheet.
If you emphasize the solving of Physics word problems in your Physics course, then the Calculator Pad section can be a great tool to reference for students. There are a wide range of problems, each with an answer and an audio-guided solution. This page has several problems which require the use of momentum conservation in order to solve. Check it out!

Minds On Physics the App, Part 3, Missions MC5 - MC10

Minds On Physics is not for the meek. But many teachers swear by it ... particularly teachers of honors, IB, and AP Physics 1. If you've not seen it in operation, it's worth taking a look. For devoted students, it can be an awesome tool. Missions M5 - MC10 on App #3 correlate with this video lesson.

Teacher Toolkit: Momentum Conservation

Try a Teacher Toolkit ... you might be very glad that you did. Each toolkit includes annotated links to vetted resources from across the web that we feel reliably support the specific topic. Give this one on momentum conservation a try.

Mutlmedia Physics Studios ... Momentum Chapter

Here is a collection of old GIF animations from one of the oldest section of our website. While the technology is admittedly old, the lessons are current. Each animation comes with a thorough and understandable explanation.
Our Tutorial section always comes through with a common sense explanation of a topic. It makes a great written reference. Many teachers link to these pages from their LMS. Check out the following two pages that are specific to this video tutorial:

The Law of Action-Reaction, Revisited
