Exploding Carts
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)
Red Cart
Mass (kg):
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?
