## Additional Learning Tools and Resources

Watching a presentation is a passive activity. Getting information is important ... but its not the destination or end point. Now that you've watched the video, its time to do something with the information you've heard. It's time to act on it. The resources below provide an opportunity to do this. We encourage learners to solidify their learning through the use of one or more of the following resources.

Concept Builders provide you with a great check up of your understanding. In this one, you are provided info about the post-explosion speeds of two carts involved in an explosion. You must identify which one(s) violate the law of momentum conservation.

Here's another Concept Builder to strengthen your conceptual understandings. 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 you to use the law of momentum conservation to complete a momentum table for a hit-and-stick collision. 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

This simulation allows you to play with variables and observe the result for a collision or an explosion. For instance, change the intiaial speed or an object or the mass of an object and analysze the system momentum. Loads of experimenting can be done; loads of learning can result.

Physics Interactives; Exploding Carts

This simulation is similar to the above but it's all about explosions instead of collisions. Alter the mass of one of the objects and observe the effect upon the post-explosion velocities of the two cars.
If your Physics course emphasizes the solving of Physics word problems, then the Calculator Pad section should become your friend. You will find problems with a wide range of difficulty levels, answers to every problem, and an audio-guided solution for every problem. 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 if you want a rigorous workout, you will find it here. Download the app to your phone or tablet, set up your account, and do some heavy conceptual lifting. And always know that a tap on the textbook icon will lead you to volumes of question-specific help.

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. Check out the following two pages for support specific to this video tutorial:
