When is Translational Momentum Conserved

Click For Summary
SUMMARY

Translational momentum is conserved in an isolated system where no net external forces act on the system. Similarly, angular momentum conservation applies under the same conditions. The relationship between momentum (p = mv) indicates that changes in momentum can arise from variations in mass (m) or velocity (v). Understanding the distinction between isolated and closed systems is crucial for applying these principles accurately.

Homework Statement



When is Translational Momentum Conserved and when is Angular Momentum Conserved?
 
Physics news on Phys.org


When no net external force acts on the system...or a net change in the content of the system (essentially an isolated system...or closed system...I forgot the difference between the two if there is any). Think of it in terms of p = mv...changes in p may occur from changes in m (mass) or v (velocity). The same applies to angular momentum.
