How do you determine conservation of momentum

[NewDaddyJones]

In my lab, I have the change in momentum = -8.00 x 10^-3 and my error of change in momentum = 1.22 x 10^-3.

Does my change in momentum have to be lower than my error of conservation in order to prove conservation of momentum? Then none of my procedures prove this, even though my average error of time is 3.95 x 10^-3.

That was wrong because you have to account for the errors of initial momentum and final momentum. I'm just asking how do you prove conservation of momentum, anyway, not any specific values.

Could you perhaps elaborate on your experiment, as well as giving us some units to your measurements.

if your measurement is 8.00 10^-3, and your error is 1.22 10^-3, then that's 8.00 ± 1.22 10^-3, which isn't zero!

Congratulations!

You have successfully disproved most of classical physics! ​
