This video discusses how to use Newton's 2nd Law of Motion to derive the impulse equation, which allows you to calculate an object's change in momentum. The video also shows experimentally that an impulse (the product of force and time) is equivalent to an object's change in momentum.
“Explosions Lab” Videos:
Below are 4 videos that can be used to introduce the concept of momentum. In the event of a two-object, linear explosion, the videos can be used to determine the relationship between the ratio of the objects' masses (mass of the red car / mass of the blue car) to the ratio of the objects' resulting velocities (red velocity / blue velocity) after the “explosion”. See the conclusion discussion video below to see how the collected data can lead to the concept of “momentum”.

Momentum Bar Graphs (Conceptual Analysis): youtu.be/bVmEPdzdZQk
This video introduces a representational tool called momentum bar graphs. It is a conceptual way to visualize the momentum of a system before and after an event. A momentum bar graph can be used to develop a momentum conservation equation which can then be used to solve quantitative problems related to momentum and impulse.
