In principle momentum is always conserved. However what sometimes happens in a collision is that energy is released that is then no longer considered part of the system.
For example if two cars collide energy could be dissipated via the air and ground (e.g. heat) and this can also carry away momentum. Often, these effects are not taken into account and in that way momentum conservation appears to be violated; but if one takes care and takes into account all collision products the total momentum after is equal to the total momentum prior.
So in short, any violation can be traced back to a redefinition of the system.
What else can I help you with?
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 during an elastic collision?
Yes, momentum is conserved during an elastic collision.
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.
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.
In a two body collision?
Momentum is always conserved
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 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.
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 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.
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.
Is the total angular momentum conserved when there is a two car collision?
In a two-car collision, the total angular momentum is conserved only if no external torque is acting on the system. If there is no net external torque exerted on the cars during the collision, the total angular momentum before the collision will be equal to the total angular momentum after the collision.
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.
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.
