Momentum is the inertial energy of a body or object, generally a term that describes the energy stored in a moving mass. It takes into account the mass of an object ( m ),… and its velocity ( v ). The formula for momentum ( p ) is: p = mv .
Related Information: With this formula, we can calculate the momentum of a given object and find out how much energy it carries. This information might be useful in the design of barriers, to stop vehicles from crossing medians and running into oncoming traffic on freeways. Examples: If someone throws a ping pong ball, it carries a certain momentum (energy). If it hits a window. Generally, the window won't break. The momentum of the ball is low enough so that the energy the ball carries is insufficient to break the window. However, if that window is struck with a brick that is thrown with the same velocity, the window will almost certainly break. The mass of the brick is much greater than that of the ball, so it carries a lot more energy with it. It's momentum is a lot greater because its mass is so much greater. Should a small fishing weight, that breaks off a line in a practice cast, strike that window, it may break the window. However, if that same mass of lead is a projectile that has just been shot out of a firearm, and hits that window, it's probably going to shatter the window and go inside and make a mess out of whatever is in its way. The velocity of that small mass of lead, is so high in the latter case, that the energy it has will be much greater than that of the cast sinker owing to its higher velocity. There are some special considerations as regards quantum mechanics and a link is provided below for anyone interested in further investigation. A Different Perspective: Momentum can be thought of as the store of energy in a moving body. This energy can be put to work. If two bodies have different masses but the same velocity then the heavier one will have more momentum. If the two bodies are equal in mass but different in velocity then the faster one will have more momentum. (MORE)

Answer #1: An Example of momentum is when a Big truck rolls down a hill, andthen a little car rolls down a hill. The Truck goes faster because it had alarger mass which gave… it more momentum. ======= Answer #2: The answer above illustrates a classic misunderstanding of gravity... one that was debunked roughly 500 years ago, but is apparently so appealingto human senses that it refuses to die. The simple fact is that if nothinginterferes with them, then the smallest lightest objects and the biggest heaviestobjects all fall at the same rate. Neglecting the change in the position of the earth, the truckslides down the hill at the same speed as the car, or any other frictionlessobject. The size of the trucks wheels does matter slightly, as larger wheels possessmuch more angular momentum , which is sort of like a measure of howmuch additional inertia an object has due to its resistance to rotation. Anothererror illustrated above is the belief that mass and momentum are the same thing.While momentum is proportional to mass, other factors are involved aswell. Momentum in Classical physics is given as follows:.
momentum = mass *velocity. .
This is inaccurate, however, if we wish to use momentum to modelenergy transfers in collisions (which is mostly what it is used for). Amore accurate formula would be something like: momentum = { (rest mass + extra mass due to motion) * velocity } + momentumdue to wave properties. where the momentum due to wave properties is given by: .
plank'sconstant / wavelength .
for light and some other mediumless waves. An example illustrating the usefulness of momentum as a concept inphysics is the idea of a solar sail, whereby a spacecraft could propel itselfby reflecting light off of giant mirrored sheets, sailing on a solar wind. Thisis only possible because light has momentum and a portion of that momentum would be transferred to the ship as the light bounced off/was reflectedby/was absorbed by the sail. (MORE)

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)

Momentum is defined as the "Mass in Motion". It is a Vector quantity. It depends on two variables (Object Mass and Velocity) . Its direction is same as objects velocity direct…ion. In physics momentum is required to specify the motion of the object . If two bodies of same masses having different velocities have different momentum , in a similar way bodies of different masses having same velocity have different momentum. So , in order to describe the motion of object clearly one of the tool in classical mechanics is momentum (MORE)

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.

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.

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.
