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.

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

When ever an object is standing still the momentum is?

When an object is still it has no momentum. That is, the momentum is zero.


What are some true statements about momentum?

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.


The product of an object mass and velocity is called its What?

That's the object's linear momentum.

What is the product of an object and the object's mass and velocity?

That's the object's linear momentum.


The product of an object's mass and velocity?

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.


Is it true that an object never loses its 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.


Object A strikes object B the momentum of object B increase what happens to the momentum of object A?

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.


Why an object will move if its velocity is constant?

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.


What moving object depends on the objects mass and velocity?

That's the object's linear momentum.


What conversation states that the momentum of an object before the collision is equal to the momentum of the object after the collision?

That law is called, precisely, the Law of Conservation of Momentum.


What is an object's mass multiplied by its velocity?
