What is momentums?

The momentum of an object is the mass (in kilograms) multiplied by the velocity (in metres per second), assuming that the speed is well below the speed of light. It is measure…d in kilogram-metres per second (kg m -1 ). If you have two objects of the same mass, the one that is moving faster has more momentum than the other. If you have two objects travelling at the same speed, the heavier one has more momentum. You could also have a light fast-moving object and a heavy, slow-moving object, and they could have the same momentum as each other. The momentum of any object is constant, unless an external force acts on it (as given by Newton's first law). If an external force does act on the object, then the magnitude of the force is proportional to the rate of change of the momentum (as given by Newton's second law). So if you push against a light object (applying a force), it will accelerate away from you at quite a high rate. However, if you apply the same force to a heavy object, it will accelerate away much more slowly. In practice, you could push against a heavy table (for example) and it might not move at all. This is only because there is an external force (gravity) holding the legs against the floor, and the friction resists your pushing. If you did this in outer space (where external forces can be ignored), the table would accelerate away from you according to Newton's second law. Conversely, an object with a non-zero momentum (i.e. an object that has some mass and which is moving) will exert a force if it hits something. This is because the moving object loses some or all of its momentum (i.e. it slows down or stops completely), and the rate at which it loses momentum is proportional to the force it exerts. Imagine a mini and a freight train both travelling at the same speed - the train has more momentum, because it is heavier. Imagine they both hit a building - they will both slow down on impact, and assume they come to a stop in the same amount of time. The train lost more momentum over the same time, so the rate of change of momentum is higher for the train than for the mini. Thus the force exerted on the building by the train is higher, and does more damage. Imagine a heavy freight train moving along with some speed, and hitting a fly that was moving in the opposite direction. The front of the train exerts a force on impact, which may be enough to crush the fly against the front of the train. So the train must have lost a little bit of momentum, but in practice you would not notice it. (MORE)

What is the momentum and derive the formula for the momentum?

Momentum is the product of the mass and the velocity of an object. It's SI unit is kgms -1 . Correct, but perhaps more easily interpreted as kgm/s.

Does a fish have momentum?

The momentum of any object is [ M V ]. 'M' is its mass, 'V' is its velocity. If the fish is moving, then [ M V ] is not zero, and it has momentum.

What is the momentum law?

The Momentum Law is Newton's 3 rd Law Action-Reaction,The sum of the forces is zero. 0 = F1 + F2 = d(p1 +p2)/dt gives teh Momentum Law: p1 + p2 = constant.
