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

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));

∙ 12y agoIn 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.

∙ 12y agoNo. 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.

∙ 12y agoConservation of momentum means that it will always be equal (I think?). Correct me if I'm wrong, someone.
Wiki User
∙ 14y agoYes. The total momentum would be the same. This is an example of the conservation of linear momentum.

∙ 12y agoNope. But the sum of the two of them after the collision
is the same as the sum of the two of them before it.

What happens to the total momentum of two objects in a system before and after interactions?
The total momentum before the collision is the same as the total momentum after the collision. This is known as "conservation of momentum".
What is the recoil velocity of the pistol when a bullet of mass 20g is fired with a velocity 150ms from a pistol of mass 2kg?
Momentum before = momentum after. Since there was no movement before, momentum before = 0 If you think of the bullet as forward/positive momentum and the gun as backward/negative momentum then the momentum of the bullet plus the momentum of the gun =0 and therefore the momentum of the bullet = the momentum if the gun. momentum = mass x velocity P=m/v 20gx150m/s = 2000g (2kg) x velocity 3000 = 2000v 3000 / 2000 = v v = 1.5m/s
What are The three stages of collision?
The three stages of collision are: 1st stage - vehicle crash, 2nd stage - human crash, and 3rd stage - internal crash.
How can you practice safety when dealing with moving objects?
Monitor, and maintain awareness of, the position, speed, and direction of all moving objects. Maintain and continuously update predictions of the future course of each moving object. Move out of the path of any moving object, i.e. get out of the way, before it reaches your position.
What would you miss if you suddenly switched from seeing with your eyes to echolocation?
You will miss seeing colors and shapes of objects as they appear before you.This is because echolocation use auditory sensor and with this you can only here
How does the momentum of two objects before a collision compare with the momentum after the collision?
conservation of momentum
What happens to the total momentum of two objects in a system before and after interactions?
The total momentum before the collision is the same as the total momentum after the collision. This is known as "conservation of momentum".
The momentum before a collision of three objects is always greater than the momentum after the collision True or false?
False - the thing to remember is that momentum is conserved.
What happens to the momentum of two objects which collide and stick together?
In a collision, a force acts upon an object for a given amount of time to change the object's velocity. The product of force and time is known as impulse. The product of mass and velocity change is known as momentum change. In a collision the impulse encountered by an object is equal to the momentum change it experiences.Impulse = Momentum Change. What happens to the momentum when two objects collide? Nothing! unless you have friction around. Momentum#1 + Momentum#2 before collision = sum of momentums after collision (that's a vector sum).
What happens when another object collides with another object?
Newton's Third Law is closely related to Conservation of Momentum. When objects collide, whether the collision is elastic or not, momentum is conserved. (An elastic collision is one in which mechanical energy is conserved. In an elastic collision, after the collision, the objects go away at the same relative speed at which they approached before the collision.)
What is the total momentum between two identical balls traveling toward each other at the same speed from opposite directions?
They have identical momentum before the collision . The total momentum will the the same before and after the collision. When the balls collide they will bounce apart both with same force and so the same momentum as originally - but in opposite directions. This assumes no energy loss in an ideal elastic collision.
How do you calculate velocity after perfectly collision?
To calculate the velocity after a perfectly elastic collision, you need to apply the principle of conservation of momentum and kinetic energy. First, find the initial momentum of the system before the collision by adding the momenta of the objects involved. Then, find the final momentum after the collision by equating it to the initial momentum. Next, solve for the final velocities of the objects by dividing the final momentum by their respective masses. Finally, make sure to check if the kinetic energy is conserved by comparing the initial and final kinetic energy values.
In an isolated system two cars each with a mass of 1500 kg collide. Car 1 is initially at rest while Car 2 was moving at 5 ms. What is their combined momentum after the collision?
Law of Conservation of Momentum: The total momentum after the collision is equal to the total momentum before the collission.
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.
What is the total momentum of marbles after the collision?
The same as the total momentum before the collision.
What does the law of conservation of momentum say about the total amount of momentum after a collision?
the total momentum after a collision must be equal the total momentum before the collision.
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.
