Would no momentum be conserved for the system if momentum were not a vector quantity?
Momentum would be 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)
What would be the momentum if the mass were halved?
momentum=mass * velocity if velocity remain unchanged, the momentum too will be halved ============================================== But wait! Haven't we all learned that momentum is conserved, and half of it doesn't just suddenly disappear ? If half of the mass of a moving object suddenly disconnects from the object and goes somewhere else, then half of the momentum must go along with that half of the mass, and the total momentum doesn't change. On the other hand, if Tinker-Bell flew by, waved her magic wand and sprinkled ferry dust on the moving object so that half of its mass truly ceased to exist, then in order to keep the total momentum constant, the object's velocity must double! The answer to the question is: No matter what happened to the massive moving object, or how it happened, total momentum doesn't change. It's the same today, tomorrow, and forever. Momentum of the total system is always conserved. If half of the mass is detached, you can't say the rest is the whole system. The whole system is together both halves. If both moving same velocity, momentum is divided. If that half stopped, half of the momentum goes to the force used to stop that.
When carts unequal masses push away from each other which cart has more momentum?
In elastic collisions, momentum is a completely conserved quantity, meaning that the total momentum of the system before the collision should equal to the total momentum of the system after the collision. In this case, the p initial was equal to 0, that means p final should have also been 0, the only way that could be achieved is if the momentum of both carts had the same magnitude but in the opposite direction. p = m*v so if p is the same, the cart with the heavier mass would necessarily have a slower speed than the light cart.
As a ball falls toward earth the momentum of the ball increases How would you reconcile this observation with the law of conservation of momentum?
The principle of conservation of momentum is not satisfied, since the sum of external forces is not equal to zero, if the ball falls the net force is equal to the weight, makes the ball Vary your speed and therefore their momentum.

Momentum would be conserved.
Why did scientists believe in a neutrino long before it was detected?
This was because of laws of conservation of: momentum, angular momentum, and energy. In certain reactions, these were apparently not conserved; a hypothetical particle would resolve the observed discrepancy.This was because of laws of conservation of: momentum, angular momentum, and energy.

If momentum were conserved the ratio of the total momentum after the collision to the total momentum before the collision would be?
1 +/- two decimal place

Distinguish beween and elastic and inelastic collision for wich type of collision is momentum conserved?
Momentum is conserved in both elastic and inelastic collisions. Mechanical energy is conserved only in elastic collisions. In inelastic collisions, part of the energy is "lost" - usually most of it would be converted to heat, eventually.
Would a larger mass moving slowly have the least momentum?
Yes, they would have a momentum. ^^
What happens if there is no rotation in solar system?
This is an impossible "what if ?" question. Angular momentum is a conserved quantity, and cannot suddenly disappear from a system. If you have a magic wand, please don't wave it; with no rotation everything that is currently orbiting the sun would disappear into it. That would give a whole new dimension to "global warming".

Conservation of angular momentum tells us?
Angular momentum will not change unless an external torque acts upon the system The short answer would be that angular momentum is conserved, i.e. it cannot be created nor destroyed. A more technical answer would be that there is a certain theorem in theoretical physics called Noether's theorem which shows that if a physical theory exhibits rotational invariance (i.e. the physics are the same even if you rotate the system) that angular momentum conservation is a result. According to particle physics therefore the conservation of angular momentum seems to tell us that the Universe is invariant under rotations. This might seem strange, because surely rotating yourself changes how think look, but the physics involved remains the same.

Suppose a train car in moving down the track at 10ms hits another train car that is not moving explain how momentum is conserved after the collision?
Conservation of Momentum:The total momentum in a closed or isolated system remains constant. If the two trains are moving as one after the collision, and were the same mass M each, the total momentum before and after the collision would be the same, ccording to the law. Before the collision, the momentum (velocity times mass) was 10 x M units (one train) which must now be the same but applied to two trains (2M) moving as one body. The Conservation of Momentum rule, will tell you that the new moving body, being twice the mass, would be moving half the velocity to conserve the momentum from before the collision.
