This Interactive allows you to explore the law of momentum
conservation for explosion-like impulses. Two carts are positioned on a
track and equipped with spring-loaded plungers. The plungers push the
carts away from each other in opposite directions.
Post-Explosion Speed (cm/s)
Vary the mass of the carts and observe the effect upon the
post-explosion velocity. Do you see a pattern? And can you use the data
to show that total system momentum is conserved?
