External forces applied to the system can change the total momentum. This includes forces from contact interactions, such as collisions, as well as non-contact forces like gravity or electromagnetic forces.

Under what circumstances is momentum not conserved?

Momentum is not conserved when external forces act on a system, such as friction or air resistance, causing a change in the total momentum of the system.


Which law states that the total momentum does not change when it's transferred?

The law of conservation states that the total momentum does not change when it is transferred.


What is change in total momentum?

The change in total momentum of a system is equal to the impulse imparted to the system. This change can result from external forces acting on the system or from internal interactions within the system. The principle of conservation of momentum states that the total momentum of an isolated system remains constant if no external forces are present.


Does every transfer decrease momentum a little?

No, not necessarily. The total momentum of a system is conserved if there are no external forces acting on it. During transfers, momentum can change between objects but the total momentum of the system remains the same.


What law states that if no net force acts on an system then the total momentum of the system does not change?

This is known as the law of conservation of momentum, which states that the total momentum of an isolated system remains constant if no external forces are acting on it.


Why is momentum conserved in a closed system?

Momentum is conserved in a closed system because there are no external forces acting on the system to change the total momentum. This principle is based on the law of conservation of momentum, which states that the total momentum of a closed system remains constant unless acted upon by an external force.


The total amount of momentum of a group of objects does not change unless outside forces act on the objects?

This statement is consistent with the principle of conservation of momentum. In the absence of external forces, the total momentum of a system remains constant. This means that the sum of the momenta of all objects in the system before a collision or interaction will be equal to the sum of the momenta after, provided no external forces are involved.


What law states that's of no net force acts on a system then the total momentum of the system does not change?

The law that states if no net force acts on a system, then the total momentum of the system does not change is the law of conservation of momentum. This law is based on Newton's third law of motion and applies to isolated systems where external forces are absent.


What is the Law of convesation of momentum?

That means that a quantity, called "momentum", can be defined, and that this quantity does not change over time. In any collision, for example, the momentum (which is defined as mass x velocity) of individual objects can change, but the total momentum does not change. Please note that since velocity is a vector quantity, momentum is also a vector quantity.


What does the law of conversation of momentum state?

The law of conservation of momentum states that in a closed system, the total momentum before a collision is equal to the total momentum after the collision, as long as no external forces are present. This means that momentum is conserved in a system if there are no external forces acting on it.


According to the law of conservation of momentum in an isolated system the initial total momentum?

In an isolated system, the total momentum remains constant if no external forces are acting on it. This means that the initial total momentum of the system will be equal to the final total momentum after any interaction or collision within the system.


What has to happen for momentum to be conserved?

For momentum to be conserved, the system must be isolated from external forces. This means that no external forces, like friction or air resistance, can act on the system. Additionally, the total momentum of the system before an interaction must be equal to the total momentum after the interaction.
