In a closed system, the TOTAL initial momentum before an "event" is the same as the TOTAL final momentum (at the end).

What is the most significant similarity between conservation of energy and conservation of momentum?
in law of conservation of energy ENERGY IS CONSERVED and in law of conservation of momentum MOMENTUM IS CONSERVED. There's not similarity in these two laws. expect that in both laws , one quantity is conserved.
Does momentum conserved during collisions?
Yes, momentum is conserved during collisions. This means that the total momentum of the objects before the collision is equal to the total momentum of the objects after the collision, as long as no external forces are acting on the system.
What is the theory of momentum?
The idea is that there is a quantity, "amount of movement", formally the product of mass x velocity, that is conserved. That means that the total momentum doesn't change, even if two objects collide, for example - any momentum lost by one object is gained by the other object.
When we say a quantity is conserved it means that what we start with is what we end up with?
Yes, the principle of conservation states that a specific quantity remains constant over time within a closed system. This means that the initial amount of the conserved quantity is equal to the final amount after any interactions or transformations occur.
The collision between two helium atoms is perfectly elastic so that momentum is conserved?
In an elastic collision, both momentum and kinetic energy are conserved. This means that the total momentum of the system before and after the collision remains the same. In the case of two helium atoms colliding elastically, the total momentum of the atoms before the collision will be equal to the total momentum of the atoms after the collision.

Is momentum conserved in a perfectly inelastic collision?
In any physical process, momentum will always be conserved. Momentum is given by p = m*v. There is also something called law of conservation of momentum.
What is the relationship between kinetic energy and the conservation of momentum in an inelastic collision?
In an inelastic collision, kinetic energy is not conserved because some of it is transformed into other forms of energy, such as heat or sound. However, momentum is always conserved in any type of collision, including inelastic collisions. This means that the total momentum before the collision is equal to the total momentum after the collision, even if kinetic energy is not conserved.
What does it meanto say that momentum is conserved?
Momentum is the product of mass times velocity. The sum of (momentum x velocity) for all parts of a closed system remains constant. For instance, if two balls collide, any momentum lost by one is gained by the other (transferred to the other). Energy is NOT necessarily conserved (kinetic energy, to be more precise - any energy lost will be converted into heat, usually), so momentum is sometimes more useful for certain calculations.
What is the momentum of a canoe?
The momentum of ANY object - not just a canoe - is obtained by multiplying its velocity times its mass.
All moving objects have momentum?
Momentum is the product of an object's mass and its velocity, and only moving objects have momentum. If an object is stationary, it has zero momentum. Momentum is a vector quantity, meaning it has both magnitude and direction, and is conserved in a closed system with no external forces acting on it.
What is conserved when two object collide in a closed system?
Momentum is conserved when two objects collide in a closed system.
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.
