A mass traverlling at a given speed/velocity.
Do NOT confuse with 'Force'.
Momentum = mass X veloicty
Force = mass X acceleration.
A car , of say mass 1 tonne, ( 1000 kg) travelling at 44 netres per sec has a momentym of = 1000 kg X 44 m/s = 44000 kg m/s
The same vehicle accelerating from 0m/s ( standing start) to 44 m/s in 10 sec has a force of
F = 1000 kg( 44 - 0 ) m/s / 10 s
F = 1000 kg * 4.4 m/s^2
F = 4400 kg m/s^2
Note the different in the time(s) units.
Answer #1:
An Example of momentum is when a Big truck rolls down a hill, and then a little
car rolls down a hill. The Truck goes faster because it had a larger 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 appealing to human
senses that it refuses to die. The simple fact is that if nothing interferes with
them, then the smallest lightest objects and the biggest heaviest objects all
fall at the same rate.
Neglecting the change in the position of the earth, the truck slides down the
hill at the same speed as the car, or any other frictionless object. The size of
the trucks wheels does matter slightly, as larger wheels possess much more
angular momentum, which is sort of like a measure of how much additional
inertia an object has due to its resistance to rotation. Another error illustrated
above is the belief that mass and momentum are the same thing. While
momentum is proportional to mass, other factors are involved as well.
Momentum in Classical physics is given as follows: momentum = mass * velocity. This is inaccurate, however, if we wish to use momentum to model energy
transfers in collisions (which is mostly what it is used for). A more accurate
formula would be something like:
momentum =
{ (rest mass + extra mass due to motion) * velocity } + momentum due to wave properties.
where the momentum due to wave properties is given by:
plank's constant/wavelength for light and some other mediumless waves.
An example illustrating the usefulness of momentum as a concept in physics is
the idea of a solar sail, whereby a spacecraft could propel itself by reflecting
light off of giant mirrored sheets, sailing on a solar wind. This is only possible
because light has momentum and a portion of that momentum would be
transferred to the ship as the light bounced off/was reflected by/was absorbed
by the sail.
C. The mass of a moving motorcycle is increased.
The best demonstration of transfer of momentum is the behavior of objects
that collide on an air-hockey table, a pool table, or a bumper-car track.

Momentum is not an object, it is energy.
Momentum = Mass x Velocity (p=mv)Of course an object at rest would have no momentum no matter what the mass is (velocity = 0 so momentum = 0).Playing volleyball with a balloon might be something that would be considered low momentum. You can hit it as hard as you like, but it has so little mass that its momentum can hardly overcome the air resistance.You might push a small car at, say 1/4 MPH, and it would have relatively little momentum.However a train traveling at the same 1/4 MPH would still have a lot of momentum.
The law of conservation of momentum is Newton's 3rd law' The vectors sum to zero: 0 = F1 + F2 = dp1/dt + dp2/dt = d(p1 + p2)/dt =0. Thus, p1 + p2 = a constant, thus, the conservation of momentum.
No it does not. It represents momentum.

law of conservation of momentum
Momentum is motion. When a car is moving it is exhibiting momentum. A young professional getting promotions is experiencing momentum.
Momentum would be an example of kenetic energy.
In an isolated system the total momentum of a system remains conserved. For example If you fire a bullet from Gun , bullet go forward with some linear momentum and in order to conserve the linear momentum the gun recoils
No, there has not been a single violation of the law of conservation of momentum.
An object at rest. Actually that's the only possible example for a single object. For two objects, you can have objects moving in opposite directions; for example, one may have a momentum of +100 units, and the other, a momentum of -100 units.
Elastic collision.
when we churn and make out butter milk out of curd, here we apply angular momentum ceiling fan is another example of angular momentum
In an isolated system the total momentum of a system remains conserved. For example If you fire a bullet from Gun , bullet go forward with some linear momentum and in order to conserve the linear momentum the gun recoils
momentum
It is called the momentum-impulse theorem and states that an impulse will change the momentum of an object. For example, if you drop an object when it hits the ground an impulse occurs. The momentum of the object also changes. Jnet = deltap, where deltap is the change in momentum.
the momentum and energy is transferred and someone gets hurt, for an example watch Clay Matthews.
Yes. For example, if both are at rest, both have zero momentum - but that's not the only case.
