Which of these leads to the conclusion that linear momentum is conserved?
The fact that the total external force acting on a system is zero leads to the conclusion that linear momentum is conserved. This is known as the law of conservation of linear momentum. If there are no external forces present, the total momentum of a system remains constant.
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.
What does conversation of momentum mean?
Conservation of momentum is a fundamental principle in physics that states the total linear momentum of an isolated system remains constant if no external forces act on it. This means that in a closed system, the total momentum before an event must equal the total momentum after the event. It is commonly used to analyze collisions and explosions.
Is an isolated system two cars each with a mass of 2000 kg collide car 1 is initially at rest while car 2 was moving at 20 ms what is their combined momentum after the collision?
Their combined momentum was 40,000 kg-m/s: 2000kg X 20 m/s= 40000 kg-m/s.
Drop a stone from the top of a high cliff identify the system wherein the net momentum is zero as t?
The system wherein the net momentum is zero at all times during the stone's fall is the stone itself. Momentum is a vector quantity, and the stone experiences an equal and opposite change in momentum at each instant due to the gravitational force. The external forces acting on the stone can be neglected in this case.

Which law states that the total momentum does not change when it is transferred?
The law that states that the total momentum of a closed system remains constant when momentum is transferred is the Law of Conservation of Momentum. This law applies to isolated systems where there are no external forces acting.
Is it true that if the total angular momentum of a system of particles is zero, then all the particles are at rest?
No, it is not necessarily true that if the total angular momentum of a system of particles is zero, then all the particles are at rest. The total angular momentum being zero means that the rotational motion of the system is balanced, but individual particles within the system can still have their own angular momentum and be in motion.
Why if total momentum is zero but kinetic energy is not equal to zero?
This sounds like a trick question. Momentum has a sign (positive or negative), and if you have two masses that are going in opposite directions their total momentum is zero. But the sum of their kinetic energies is positive.
Does an isolated system have net force acting on it?
Even if it does the net force acting on it should be zero. That's why it's called isolated.
When two billiard balls collide the total change in momentum is what?
When two billiard balls collide, the total change in momentum is equal to zero according to the law of conservation of momentum. This means that the combined momentum of the two balls before the collision is equal to the combined momentum after the collision.
What is torque when angular momentum is constant?
When angular momentum is constant, torque is zero. This means that there is no net external force causing the object to rotate or change its rotational motion. The law of conservation of angular momentum states that if no external torque is acting on a system, the total angular momentum of the system remains constant.
What is the momentum of zero?
The momentum of an object with zero velocity is zero. Momentum is calculated as mass multiplied by velocity, so if velocity is zero, momentum will also be zero.
