Yes, momentum is conserved in the larger apple-Earth system. When the apple falls towards Earth, it gains momentum in the downward direction while Earth gains an equal amount of momentum in the opposite direction. The total momentum of the system remains constant, demonstrating the principle of conservation of momentum.
No, momentum conservation is a fundamental principle in physics and it would still hold even if momentum were not a vector quantity. Momentum conservation simply states that the total momentum in a system remains constant unless acted upon by an external force. Whether momentum is treated as a vector or scalar quantity does not change this principle.
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)
No, momentum is conserved in the absence of external forces, so the momentum of the rock would remain constant as it falls to the ground. The only force acting on the rock would be gravity, which does not change the momentum of an object in free fall.
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.
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.

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.

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.

No, momentum is given by the product of an object's mass and its velocity, so a larger mass moving slowly could still have significant momentum. Momentum depends on both mass and velocity, so even if an object is moving slowly, a large mass can still have considerable momentum.
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".

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.
Strictly speaking, you would say that a force acts on a system and the impulse of that force corresponds to the change in momentum of the system due to the action of the force. More mathematically, the impulse of a force is defined as the integral of that force with respect to time over the time period that the force acts.
