## Proportional Reasoning and Collisions Analysis Video Tutorial

Physics formulas can be more than a recipe for plug-and-chug problem-solving. They can also be a powerful guide for thinking about the effect of variables on a physical situation. The Proportional Reasoning and Collisions Analysis Video Tutorial explains how to use momentum and momentum conservation to analyze hit-and-stick collisions and quickly determine the after-collision speed of objects.. Numerous examples, illustrations, and animations assist in the explanations. The video lesson answers the following question:

1. How do you combine proportional reasoning and momentum conservation to predict the post-collision velocity of a hit-and-stick collision?

To improve the effectiveness of the learning experience, The Physics Classroom has provided the following tools:

Lesson Notes
The Lesson Notes are intended to be printed and used when watching the video. They are structured to allow students to follow the video, record some notes, and leave the video with a document that can be referred to as their learning continues. The Lesson Notes are available as a PDF. Permission is granted to print the notes or to include a link to them from a learning management system.

Learning takes effort. Watching a video is a relatively passive activity. It's one thing to listen to a video presented by a person who understands the material. But it's quite another thing to apply the information from the video in an effort to personally understanding the material. This page lists a variety of tools that can used to put the new learning to use. The tools include those that can be used by students and those that can be used by teachers with their students within the classroom. Related resources are also included among these tools.
