Momentum is ALWAYS conserved. To get some interesting examples, think of any situation where the velocity of some object changes - this will change the object's momentum. There will always be some other object whose momentum changes in the opposite direction - the object can be figured out by Newton's Third Law. For example, if a car accelerates or brakes, the interaction is between the car and Planet Earth, so the planet will accelerate in the opposite direction as the car.

∙ 14y agoA really good example, and one you've probably seen before is the toy Newton's Cradle. Five balls suspended on strings hang in a line, you pull one back and release it, the one on the opposite end swings forward.

∙ 13y agoThe Earth, in its accretion phase, collected lots of bits of rock etc, and the spin we are left with is the nett spin force of the whole collection. The Earth has continued spinning for a few billions of years. This is an example of conservation of momentum.
As an aside, some of Newton's laws apply to interactions between people as well!

∙ 11y ago1) You fire a gun, say. The bullet moves forward, but nature says that the total momentum has to be conserved - so surely there has to be an equal momentum backwards somewhere? And there is - you feel the effect of firing the gun by being jolted backwards.
But why does the bullet move so fast and you move so slowly compared to it? Surely they are not balanced? Well - Newton told us that p=mv (momentum is mass multiplied by velocity). The bullet has very little mass, so with a given momentum it has to move really fast. But you have a large mass compared to it - so for the same momentum you only have to move slowly.
This is a commonly used consequence of the conservation of momentum.
2) Here is a better one (conservation of angularmomentum)
You are in a playground; you're in one of those spinny things that children ride around on. When you move to the centre, you find that you start to speed up, rotating faster. When youmove back awayyou slow back down again.Why? Newton says that L = mvr (angular momentum is mass times velocity times radius from the centre of rotation). Therefore if you decrease the radius, you increase either your mass or your velocity to keep momentum conserved. Clearly you are only going to increase velocity.
This was my favourite.

that's available to almost everybody ... is to watch everything that happens on a

What is an example of an event when momentum is not conserved?
No, there has not been a single violation of the law of conservation of momentum.
What are 3 laws of nature?
For example, various conservation laws (conservation of mass, of energy, of momentum, of angular momentum, of electric charge), Newton's Second Law, the Universal Law of Gravitation, etc.
What is a sentence using the law of conservation of momentum?
Conservation of momentum is an absolute symmetry of nature
What states that the total momentum of objects that interact do not change?
You have more or less described a law of physics known as conservation of momentum, which is not the same thing as the law of universal gravitation. The law of universal gravitation describes the way mass attracts other mass, and the law of conservation of momentum tells us that momentum is neither created nor destroyed. These two laws are not connected.
What is the relationship between momentum and law of conservation of momentum?
Well... the law of conservation of momentum states that "In a system consisting of bodies on which no outside forces are acting; the total momentum of the system remains the same."
What is an example of an event when momentum is not conserved?
No, there has not been a single violation of the law of conservation of momentum.
How does the law of conservation apply to a game of pool?
There are several laws of conservation; please clarify which one you mean. For example, there is the law of conservation of mass, of energy, of momentum, of rotational momentum, of electrical charge, and others.
Year the law of conservation was discovered?
There are many laws of conservation. Some of the better-known ones are the law of conservation of energy, of momentum, and of rotational momentum.There are many laws of conservation.

How can before and after situations be compared for collisions using the law of conservation of momentum?
The momentum before and after is the same, due to the Law of Conservation of momentum. Thus if you calculate the momentum before, then you have the after momentum or vice-versa.
Law of the conservation of angular momentum applies which body?
Law of conservation of momentum applies to any body on which no external torque is acting.
Is it true that the law of conservation of energy stated that momentum is conserved in a collision?
Is it true that the law of conservation of engery states that momentum is in a collision

What is the most significant similarity between conservation of energy and conservation of momentum?
in law of conservation of energy ENERGY IS CONSERVED and in law of conservation of momentum MOMENTUM IS CONSERVED. There's not similarity in these two laws. expect that in both laws , one quantity is conserved.
