When three balls collide they bounce off each other and roll away but they eventually stop does this violate the law of conservation of momentum?
No, this does not violate the law of conservation of momentum. When three balls collide, the total momentum before the collision is equal to the total momentum after the collision. Although the balls may roll away and eventually stop due to friction and other external forces, the total momentum of the system remains conserved.
When two bodies having same momentum collide what will be the result?
There are two possible results. However, they cannot move in the same direction after the collision.Total initial momentum = p - p = 0where p represent the momentum of each object.From the principle of conservation of momentum;Total initial momentum = Total final momentumThus, Total final momentum = 0There are only two possibilities for this:1. Kinetic energy is conserved. (the collision is perfectly elastic)In this case, they would move away from each other with the same magnitude of initial momentum.2. Kinetic energy is not conserved. (the collision is inelastic)In this case, they would either remain at rest or they will move away from each other with a smaller magnitude of initial momentum each had.Note that if both bodies had moved in the same direction, there would be a net momentum in this direction and momentum would not have been conserved. (Momentum is ALWAYS conserved provided there is no external force acting on the system)
Why in a collision momentum is not always conserved?
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.
When carts unequal masses push away from each other which cart has more momentum?
The cart with the greater mass will have more momentum when they push away from each other, assuming they have equal velocities. Momentum is the product of an object's mass and velocity, so the cart with greater mass will possess more momentum.
How does the electric force between charged objects changed as the objects move away from each other?
The electric force between charged objects decreases as the objects move away from each other. This decrease is described by Coulomb's law, which states that the force is inversely proportional to the square of the distance between the objects.
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 keeps the planets and other solar system objects in orbit around the sun?
The force of gravity is what keeps planets and other objects in orbit around the sun, along with the angular momentum of the planets and objects. Without gravity, they would just fly away into space, and without angular momentum, they would just fall into the sun. But both of those together produce orbital motion.
When carts unequal masses push away from each other which cart has more momentum?
The cart with the greater mass will have more momentum when they push away from each other, assuming they have equal velocities. Momentum is the product of an object's mass and velocity, so the cart with greater mass will possess more momentum.
How can you get away in a frictionless surface?
You have to get rid of mass. Throw things, spit, fire a gun if you have one, etc. Since momentum is conserved, every time you get rid of something, you move across the ice in the opposite direction.
Why is a neutrino released during positron emission?
To preserve the conservation of; energy, momentum, and angular momentum in beta plus decay. Without the neutrino there is a measurable difference between the energy, momentum, and angular momentum of the initial and final particle. The neutrino rectifies this difference and it's existence was actually postulated before it was ever discovered!
Change of color on the spectrograph as objects move toward or away from other objects?
Doppler shift

What is a good example of the law momentum?
an example you can try for yourself is to sit on an office chair on a smooth surface throw a heavy object away from you, as this object you have thrown had been given a velocity to conserve momentum you will travel backwards somewhat however you are likely to slow down rapidly due to friction. a more observable example is the firing of a cannon, which moves back significantly after being fired, this recoil is the effect of momentum being conserved.
Why does a golf ball make a bigger dent in the sand when dropped above the sand at higher heights?
It has more momentum from a higher height. Because momentum is always conserved, and momentum is the product of mass times velocity, more sand particles must move away faster in order to conserve the momentum of a heavy ball moving fast. The ball is moving faster from a higher height because the acceleration due to gravity (-9.81 m/s^2) increases the velocity of a falling object after each second its been falling.
