That simply means that the total momentum before and after the crash is the same. Please bear in mind that momentum is a vector quantity. Thus, for example, one car moving at 20 m/s (that's 72 km/hour) north, and another car (same mass) that moves at 20 m/s south have a total momentum of zero, because of the way vectors are added.

When is momentum conserved in a collision?

Momentum is conserved in a collision when there are no external forces acting on the system.


Is momentum conserved in an elastic collision?

Yes, momentum is conserved in an elastic collision, meaning the total momentum of the system before the collision is equal to the total momentum after the collision.


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.


Is momentum conserved during an elastic collision?

Yes, momentum is conserved during an elastic collision.


What is one example of conserved momentum?

One example of conserved momentum is a collision between two objects where the total momentum before the collision is equal to the total momentum after the collision. This is known as conservation of momentum.


Which two properties of the system are conserved by the collision?

In an isolated system, both momentum and kinetic energy are conserved during a collision. Momentum is conserved because the total momentum before the collision is equal to the total momentum after the collision. Kinetic energy is conserved if the collision is perfectly elastic, meaning there is no energy lost to other forms (e.g., heat or sound).


How is momentum conserved in your choice of two of these collisions?

In an elastic collision, momentum is conserved because the total momentum of the system before the collision is equal to the total momentum of the system after the collision. In an inelastic collision, momentum is also conserved overall, but some of the kinetic energy is transformed into other forms of energy, such as heat or sound, during the collision process.


Is momentum conserved in elastic collisions?

Yes, momentum is conserved in elastic 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.


In an inelastic collision the final total momentum is?

In an inelastic collision, the final total momentum is conserved. This means that the total momentum before the collision is equal to the total momentum after the collision, even though kinetic energy may not be conserved.


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 an inelastic collision?

In an inelastic collision, momentum is not conserved. This is because some of the kinetic energy is converted into other forms of energy, such as heat or sound, during the collision.


What is conserved in an inelastic collision and how does it affect the outcome of the interaction?

In an inelastic collision, momentum is conserved. This means that the total momentum of the objects before the collision is equal to the total momentum after the collision. The conservation of momentum affects the outcome of the interaction by determining how the objects move and interact with each other after the collision.
