What factors do you think may cause there to be a difference between the momentum before and the momentum after the collision?
There is a Law of Conservation of Momentum, which states that total momentum is always conserved. In this case, that means that - assuming no additional bodies are involved - the total momentum before the collision will be the same as the total momentum after the collision. It doesn't even matter whether the collision is elastic or not.
When momentum can be conserved?
Momentum is always conserved. No matter what the collision, as long as you look at everything involved, momentum will always be conserved.
How does conservation of momentum apply to collisions?
Momentum is always conserved. But if you want to verify, calculate the vector sum p = mv of both objects before the collision, and then calculate the vector sum p = mv of both objects after the collision. Your two vectors should be exactly equal.
Give two examples showing the conservation of momentum give one example where momentum is not conserved?
Momentum like mass will always be conserved in any process. Momentum is the product of mass and velocity of the object. It is symbolically denoted as p=m*v where p = momentum, m = mass and v = velocity
The collision between two helium atoms is perfectly elastic so that momentum is conserved?
Momentum is always conserved in any type of collision. Energy conservation, however, is dependant on elasticity. In a perfectly elastic collision all energy is conserved.
The momentum before a collision of three objects is always greater than tha momentum after the collision?
No. Newton's first law of motion states that the momentum of a system is conserved as long as there's no external force being applied on the system.
The momentum before a collision of three objects is always greater than the momentum after the collision?
Negative negative, and quite false as well.Regardless of how many objects are involved, and as long as the collisions are'elastic' ... meaning that no energy is lost in crushing, squashing, pulverizing, orheating any of the objects ... the grand total of all their momenta (momentums)after the collision is exactly the same as it was before the violence erupted.

Is momentum conserved in inelastic collision?
The energy of the momentum in a collision is conserved through the following occurrences; movement of vehicle(s) after impact, deformation of the vehicle(s) or objects hit, heat and sound.
When momentum can be conserved?
Momentum is always conserved. No matter what the collision, as long as you look at everything involved, momentum will always be conserved.
In a two body collision?
Momentum is always conserved
State and prove the law of conservation of momentum?
It states that, "Total momentum of a group of objects in a collision always remains constant provided no external force acts on them" . Mathematically it is written as, m1VI+m2V2=m1VI'+m2V2'

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.

How is the collision of a cue ball and a billiard ball an example of newton's third law and the consevation of momentum?
That simply means that the total momentum before the collision is the same as the total momentum after the collision.
