When is angular momentum conserved?
Angular momentum is conserved when there is no net external torque acting on a system. This principle is described by the law of conservation of angular momentum, stating that the total angular momentum of a system remains constant if there are no external influences causing a change.
Is momentum conserved when two lumps of clay with equal and opposite momenta have a head on collision and come to rest?
The momentum of the two lumps of clay are the same since the momentum is the same before and after the collision. The kinetic energy is not conserved but transformed into gravitational potential energy (GPE) since the position of motion has changed. *Keep in mind: KE is the energy of motion. GPE is the energy that something posses due to its position. :)
When momentum can be conserved?
Momentum can be conserved when the total external force acting on a system is zero. In these cases, the total momentum of the system remains constant before and after the interaction. This principle is commonly observed in situations involving collisions, explosions, or interactions between objects.
When is momentum conserved?
its not possible.. momentum is always conservedYou could say that momentum, in its classical definition, is not conserved at relativistic velocities. Momentum is conserved at relativistic speeds if momentum is redefined as; p = γmov where mo is the "rest (invariant) mass" and γ is the Lorentz factor, which is equal to γ = 1/√(1-ʋ2/c2) and ʋ is the relative velocity. Some argue that the relativistic mass, m' = γmo, is unnecessary, in which case the proper velocity,defined as the rate of change of object position in the observer frame with respect to time elapsed on the object clocks (its proper time) can be used.Proper velocity is equal to v = γʋ, so p = mov. mo here is the invariant mass, where before it represented the "rest mass."The problem with Newton's p = mv, is that with this definition, the total momentum does not remain constant in all isolated systems, specifically, when dealing with relativistic velocities. Mass and or velocity is dependent on the relative velocity of the observer with respect to the isolated system.It is important to add that with this new definition momentum is conserved. With that said, my point is not to argue that momentum is not always conserved but to simply offer an explanation for the relatively (no pun intended) common statement "momentum is not conserved in ALL isolated systems" which could be where the original question stems from.
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.

Why is the momentum of a roller skater is not conserved?
The situation is not quite clear. Total momentum is always conserved, but momentum can be transferred from one object to another.

In a two body collision?
Momentum is always conserved
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 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 when two or more objects push away from each other?
Yes, momentum is conserved in a system when two or more objects push away from each other. The total momentum before the interaction is equal to the total momentum after the interaction if no external forces act on the system.
When is momentun and total energy conserved?
Momentum and total energy are conserved when there are no external forces acting on a system. This can occur in isolated systems or when external forces are negligible compared to internal forces. Examples include collisions in the absence of friction or air resistance.
When a cannonball is fired is momentum conserved for the cannonball system as a whole?
Yes, momentum is always conserved in a system unless acted upon by an external force. When a cannonball is fired, the momentum of the cannonball system as a whole remains constant because the momentum of the cannonball is equal and opposite to the momentum of the recoil of the cannon.
