Okay, so I did an elastic collision with Vernier carts and magnets.
The results seem pretty good.
Cart one started with -0.1205 kg*m/s ended with +0.1027 kg*m/s
Cart two started with +0.1174 kg*m/s ended with -0.1118 kg*m/s
So Total before = -0.0031 kg m/s and total after = -0.0091 kg m/s. If I use the total before as the expected value I get 200% percent error.
While true, that seems like it is missing the point. The final value doesn't actually seem that far off from the initial value. It's close to 0 before, it's close to 0 after. But tiny differences are causing big errors.
Thoughts on how to better analyze 'Was momentum conserved?'
