If two objects collide they each have the same momentum as they had before the collision?

Answer 1

The momentum of this case is equal to the summation of cross product of mass and velocity of both. How ever after the collision, some energy is converted into other form like sound and heat. This phenomena caused the momentum efficiency (e)

In this case (masses are equal), e is equal to the ratio of the velovities summation of both masses between after and before hitting each other.

e = ((V1'+V2')/(V1+V2));

Answer 2

In an isolated system where there are no external forces, the total momentum of the system is conserved during a collision. This means that the sum of the momenta of the two objects before the collision is equal to the sum of their momenta after the collision. So, while the individual objects may exchange momentum during the collision, the total momentum remains the same.

Answer 3

In general, each object's momentum changes. But if you add the two of them

together, then the sum after the collision is the same as the sum before collision.

Now that you know the rule, there's more to it than that. The collision has to

be the kind that's called an "elastic collision", where no energy is lost. Billiard

balls do that pretty well. Cars, beanbags and slush-balls don't.

Answer 4

No. While there are many factors that are not stipulated here, lets go with the basic assumption that 2 objects are moving towards each other and the collision is head on. We will not consider other VERY contributing factors such as friction and by what means the objects are moving.

If the objects are moving at the same rate the equal forces will cancel each other out and bring both items to a standstill.

On the other hand, If one object is moving faster than the other, this object will transfer the difference of the energy outputs to the other object upon collision. example 2 objects one moving 50 feet per second (object A) and the other moving 70 f/s (object B). the difference is 20 f/s. Upon collision, the object A will cancel the 50 f/s of the colliding object B with 20 f/s left over. This left over 20 f/s is still moving in the same direction and will transfer from object B to Object A which will then begin to move in the opposite direction at 20 f/s.

Any variable will have an affect on transfer of momentum, such as angle of collision, environmental variables, and power sources.

Answer 5

Conservation of momentum means that it will always be equal (I think?). Correct me if I'm wrong, someone.

Answer 6

Yes. The total momentum would be the same. This is an example of the conservation of linear momentum.

Answer 7

the forward moving part pass speed to the object hit

Answer 8

Nope. But the sum of the two of them after the collision

is the same as the sum of the two of them before it.

Answer 9

conservation of momentum

Answer 10

yes
