What is an angular momentum?

An angular momentum is the vector product which describes the rotary inertia of a system around its axis and is conserved in a closed system.


What is angular mementum?

Angular momentum is the moment of momentum, a conserved vector quantity used to state the overall condition of a physical system.


When there is no external force acting on a body , which physical quantity is conserved?

Angular Momentum. The conserved quantity we are investigating is called angular momentum. The symbol for angular momentum is the letter L. Just as linear momentum is conserved when there is no net external forces, angular momentum is constant or conserved when the net torque is zero.


When is angular momentum conserved?

Always.Always.Always.Always.


Is the total angular momentum conserved when there is a two car collision?

Total angular momentum is always conserved - there is no way you can violate that law. So, the answer is yes.

Momentum would be conserved.


Why did scientists believe in a neutrino long before it was detected?

This was because of laws of conservation of: momentum, angular momentum, and energy. In certain reactions, these were apparently not conserved; a hypothetical particle would resolve the observed discrepancy.This was because of laws of conservation of: momentum, angular momentum, and energy.

What is always conserved?

There are several conservation laws in nature: conservation of mass, conservation of energy, of momentum, of angular momentum, of electric charge, and others.
