When is the angular momentum of a system not conserved?
The angular momentum of a system is not conserved when a net external torque acts upon the system.
What must be exerted on an object to change the angular momentum?
A torque.
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.
What is the law of inertia for rotating systems in terms of angular momentum?
An object or system of objects will maintain its angular momentum unless acted upon by an external net torque.
Is Angular accelration is produced by torque?
no angular acceleration is not producd by torque is a factor of torque T= anguar aceleration X momentum I say yes, because torque is another word for a couple that is equivalent to two equal parallel forces in opposite directions but separated by a distance. Torque acting on an inertia produces angular acceleration exactly as a force acting on a mass produces linear acceleration. Actually the answer above does not make much sense to me. Angular momentum is the angular rotation speed times the inertia. Finally inertia is the sum of all the bits of mass each multiplied by the square of distance from the inertial centre.
Momentum is to force as angular momentum is to what?
Torque
How angular momentum of the earth remain constant?
As there is no external torque acting on it, its angular momentum remains constant. This is according to the law of conservation of angular momentum
When is the angular momentum of a system not conserved?
The angular momentum of a system is not conserved when a net external torque acts upon the system.
What must be exerted on an object to change the angular momentum?
A torque.
What is the name of the mechanism that produces the amount of torque?
An angular force would produce a large torque like angular momentum of a spinning wheel.
If the torque of the rotational motion be zero then the constant quantity will be?
angular momentum
What is the name of the mechanism that produces the greatest amount of torque?
An angular force would produce a large torque like angular momentum of a spinning wheel.
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.
What is the law of inertia for rotating systems in terms of angular momentum?
An object or system of objects will maintain its angular momentum unless acted upon by an external net torque.
Law of the conservation of angular momentum applies which body?
Law of conservation of momentum applies to any body on which no external torque is acting.
What quantities are needed to calculate angular momentum?
"Rate of change" means that you divide something by time ("per unit time" or "per second"), so you would use the units of angular momentum, divided by seconds.I am not aware of any special name for this concept.
Can a particle rotate without experiencing any torque?
Yes. Without torque, a rotating object will continue rotating indefinitely, due to conservation of angular momentum.
