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 Builder: Law Enforcement - Explosions
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.
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 or both carts and observe the effect upon the post-explosion velocities of the two carts.
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.
The Calculator Pad, Momentum and Collisions Section, Problems #12-#16
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 explosion problems (#12 - #16) which require the use of momentum conservation. 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.
