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.
The conservation of momentum is most closely related to?
It is closely to Newton's Third Law - since in an action and reaction pair, momentum "gained" by one object will be "lost" by the other.
How does the law of conservation of momentum relate to work?
It relates to work in the sense that work involves moving things, which involves changing their momentum, and to change momentum you have to create an equal and opposite momentum so that momentum is conserved - although the planet Earth is such a convenient momentum sink that in most cases this happens without being specifically noticed.
How is it possible that two moving objects can collide and stop moving?
This can happen if they move in opposite directions, and the sum of their momentum is zero. For example, before the collision one may have a momentum of 100 kg x meter / second to the right, and the other 100 kg x meter / second to the left. Thus, their total momentum before the collision would be zero; therefore this would be no problem from this point of view, since the total momentum after the collision is obviously also zero. From the point of view of conservation of energy, mechanical energy is often lost in collisions; most of such energy is converted into heat energy.
Newton's third law states?
Newton's third law is..."For every action there is an equal and opposite reaction."This is probably the hardest law to really understand.It really helps to understand this law if you understand that the law has its origin in the conservation of momentum principle.The fact of the matter is, force can be most fundamentally understood to be the rate of change of momentum.Let me explain why.First momentum is..P=mvNow look at the equation for force.F=maIt is very similar except that in place of P we have F and in place of v we have a.Looking at the force equation again..f=mawe note that acceleration is the rate of change of velocity so...F=m dv/dtNow since the mass, m, is constant we can put it directly beside the velocity like so..F=d(mv)/dtThis is looking more like the below momentum equation...P=mvThe only difference is that for the momentum equation, we have, mv, and for the force equation we have the rate of change of, mv, or, d(mv)/dtNow in the force equationF=d(mv)/dtbecause P = mv, we can replace, mv with P...F=dP/dtAs I said, force is the rate of change of momentum.Now since the law of conservation of momentum states that momentum is neither created nor destroyed, if an object picks up momentum, another object to lose momentum. In Newton's third law the "action" force is the second body picking upmomentum and the "reaction" force is the first body losing that momentum.As an example, imagine two people standing on a very slippery skating rink, because they are standing still, together, they have zero momentum. If one person pushes the second person, or "applies a force" on the second person, the second person has momentum delivered to them and that second person picks up speed/momentum in that direction. The first person however picks up speed/momentum in the other direction, which means that he also had momentum delivered to him. That second person picking up momentum was the "action force", and that first person picking up momentum in the other direction was the "reaction force".The second person picked up momentum in one direction, and since there is the conservation of momentum law, the first picked up momentum in the opposite direction. Their momentum was zero before the event and since momentum has direction the sum of both momenta add up to zero after the event.If both people had been moving, for example, to the right and the first person pushed the second person also to the right, the second person would have picked up momentum to the right and the first person would have only lost momentum to the right. There would have still been both an action and a reaction force however because momentum was only exchanged.

When does a pendulum have the most momentum?
When the pendulum is at its lowest point, it has the least potential energy. Therefore, logically, due to conservation of energy, its kinetic energy is at its maximum. Therefore its speed is also at its maximum, as well as its momentum (velocity x mass).
What is the meaning of the idiomatic expression-as a general rule?
The most common or expected thing to do.
What is the mass of an object multiplied by its velocity?
The product of mass and velocity of an object is its momentum.
Why do planets rotate around the sun in the same direction?
They don't rotate in the same direction. But most of the rotation comes about from the conservation of angular momentum. Angular momentum is given by L=m*w*r2 where m is the mass, w is the angular velocity in radians per second, and r is the radius of the circular motion. Due to conservation of angular momentum, if the radius of the orbit decreases, then its angular velocity must increase (as the mass is constant). Hope I answered your question...

What does the expression is at most mean?
The expression, "is at most" is stating that there is no higher terms than what is being stated.
