The momentum of an object can be calculated by the formula mv=momentum where m is the mass and v is the velocity.
Here is another formula that may be of some help (it is the formula for the impulse-momentum relationship):
Ft=(delta)(mv)
F stands for the impact force and t stands for the impact time. Ft together equals the impulse. m stands for the mass and v stands for the velocity. (delta)(mv) together equals the change in the momentum.
The equation is:
In any closed system,
Final total momentum = Initial total momentum

For mathematical purposes:
In relation to collisions:
Total momentum is conserved, assuming a closed system of forces.
If you have two bodies colliding, A and B, the change in the momentum of A will be equal to the negative change in momentum of B. This is because of Newton's 3rd Law (action and reaction forces equal and opposite).
ΔpA = -ΔpB (where p is momentum)
That in itself already represents the concept of the conservation of momentum, but if you want to break it down further:
Substituting the equation p = mv into the above equation,
mAvA - mAuA = - ( mBvB - mBuB), or
mAuA + mBuB = mAvA+ mBvB (equation 1)
where m is mass, u is initial velocity and v is final velocity.
This means that total initial momentum = total final momentum, which is the law of conservation of momentum.
If you're dealing with elastic collisions, you can simplify it to this:
uA - uB = vB - vA
If you want to prove it, substitute equation 1 into Ek = (1/2)(mv2) and call the resulting equation "equation 2". Then solve equation 1 and equation 2 to get the simplified equation shown above.
Please note this simplified equation is ONLY for elastic collisions because it is only in ellastic collisions that kinetic energy is also conserved.
P=mv
P=momentum
m=mass
v=velocity
The units are kg m/s.... commonly referred to as a Carson.
Mass*Velocity
Where mass is in kilograms and velocity is in meters per second.
The units of momentum are kgms^-1
Velocity is distance per unit time, and so..
d=vt
Rearranged you get
v =d/t
d is the distance it travels in time t
Momentum (p) is mass (m) times velocity (v), so p = mv
product of mass and velocity (mXv)is called movement. mass in kgs, velocity in meter/sec
Its Mass and the speed of its motion.
Momentum = mass x velocity
0.5 m/s
or
5.0 m/s
When an object is still it has no momentum. That is, the momentum is zero.
Momentum can be transferred from one object to another. Momentum can be slowed by an intervening object. Momentum can be hastened by an intervening object.
momentum is equal to the mass of an object x velocity of an object
The product of an object's mass and velocity is called it's momentum. It is mostly called it's linear momentum to differentiate from the term angular momentum.
Momentum is related to velocity and mass. When an object's velocity is zero relative to its surroundings, it has no momentum. Therefore it is untrue to say that an object never looses its momentum.

You can't think of momentum as simply "increasing" and "decreasing" - you have to consider momentum as a vector.If in a collision one object's momentum changes by a certain amount, call it "a", the momentum of the other object will change by the opposite amount, "-a" - both "a" and "-a" are vectors that add up to zero. If you consider only the magnitudes of the momentum, by conservation of energy the momenta can't both increase - but they can certainly both decrease, when objects collide head-on.
Momentum. If an object has constant velocity, the object will move because it has momentum. Momentum tends to stay the same unless changed by a force.
That's the object's linear momentum.
That law is called, precisely, the Law of Conservation of Momentum.
mass x velocity = momentum. (velocity = speed with a direction)
