The law of conservation of angular momentum states that the angular momentum of a closed system is conserved if there are no net externalMultiple choice question.changes to it.factors acting on it.torques on it.forces on it.

In a closed system, angular momentum is conserved when:Select one:a.There are no external forces acting on the systemb.The system is not rotatingc.External torques acting on the system are zerod.There is no friction in the system

The statement that if there are no net external torques on a closed system, then its angular momentum is conserved is the of of .

Which law is used to describe the property of a spinning object for which the only way that the direction of rotation can be changed is by applying a torque?Multiple choice question.the law of conservation of linear momentumthe law of conservation of energythe law of conservation of angular momentumthe law of conservation of torque

Which of these statements is a consequence of the first law of thermodynamics The total linear momentum is conserved The total angular momentum is conserved The total mass is conserved The total energy is conserved

Which of the following is a necessary condition for the total momentum of a system to be conserved?*Kinetic energy must not changeNo net force acts on the systemThe system must be at restOnly the force of gravity acts on the system
