How do you determine conservation of momentum

AI Thread Summary
To determine conservation of momentum, the change in momentum must be within the range of measurement error. In this case, the change in momentum of -8.00 x 10-3 is not zero when considering the error of 1.22 x 10-3. This indicates that the experiment does not prove conservation of momentum, as the measured value does not fall within the acceptable error range. Additionally, it is crucial to account for errors in both initial and final momentum measurements. Understanding these principles is essential for accurately assessing conservation of momentum in experiments.

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! :approve:

You have successfully disproved most of classical physics! :wink:​
 

Thread 'Derivation of Hamilton's Principle: Questions'

I have recently been really interested in the derivation of Hamiltons Principle. On my research I found that with the term ##m \cdot \frac{d}{dt} (\frac{dr}{dt} \cdot \delta r) = 0## (1) one may derivate ##\delta \int (T - V) dt = 0## (2). The derivation itself I understood quiet good, but what I don't understand is where the equation (1) came from, because in my research it was just given and not derived from anywhere. Does anybody know where (1) comes from or why from it the...
