As with collisions, this interactive physics tutorial shows students how momentum is conserved in explosions.

Students learn that total system momentum is conserved for collisions occurring in isolated systems. They will find out what makes a system of objects an isolated system, and whether momentum conserved if the system is not isolated.

Two complete tutorials on momentum and its conservation. Tutorials include informational text, interactive activities, animations, and quick, interactive comprehension checks throughout the lessons.

In this physics tutorial, the law of momentum conservation will be combined with the use of a momentum table and some algebra skills to solve problems involving collisions occurring in isolated systems.

In this interactive physics tutorial, students will take a more qualitative approach to some collision problems. The questions provide a real test of conceptual understanding of momentum conservation in collisions.
