An object that decreases its speed also decreases the magnitude of its velocity and decreases the magnitude of its momentum.

Momentum is mass time velocity. Less velocity, less momentum.

Technically, velocity is a vector and therefor momentum is a vector.

One can speak of smaller or larger magnitudes of a vector, but not smaller and larger vectors because vectors have magnitude and direction. Speed is the magnitude of velocity.

Answer #1:

its kinetic decreases

==========================

Answer #2:

Makes sense, I guess! The only way to decrease the mass of a moving object

is to break pieces off of it, and when you do that, each little mass that you

throw away carries away some kinetic energy with it.

Momentum is mass x velocity; so if the magnitude of the momentum decreases, that means that the magnitude of its velocity decreases as well - assuming no mass is added or taken away.

Momentum is mass x velocity; so if the magnitude of the momentum decreases, that means that the magnitude of its velocity decreases as well - assuming no mass is added or taken away.

Momentum is mass x velocity; so if the magnitude of the momentum decreases, that means that the magnitude of its velocity decreases as well - assuming no mass is added or taken away.

Momentum is mass x velocity; so if the magnitude of the momentum decreases, that means that the magnitude of its velocity decreases as well - assuming no mass is added or taken away.

What is veocity?

The speed of an object in a particular direction.


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.


What happens to the thermal energy of an object as temperature decreases as it increases?

it decreases because when an object is moving as the temperature decreases the object decreases


If velocity decreases then does its momentum?

Momentum is the product of mass times velocity. With less velocity, there will be less momentum. (An object's mass will usually not change.)


Does every transfer decrease momentum?

No. Total momentum always remains constant. Therefore, if the momentum of one object decreases, the momentum of another must needs increase.


What happens to the momentum of one object when it colides with another object if they are travelling in the same dirction?

Some momentum is transferred from one to the other.


What happens to the momentum if the mass of the object increases?

How do the mass and velocity of a moving object affects its momentum?

As the velocity decreases, the momentum increases. Mass is the matter inside of something and momentum is how hard it is to stop something. Therefore momentum needs mass to function because without mass there would be no momentum. So think of the sentence above like this: velocity ( a measure of momentum) decreases, the momentum (including mass inside an object) goes up therefore making the mass increase while the velocity decreases.


What happens to the angular velocity of an object as it starts to decrease in size?

Because momentum is conserved, if the size or mass decreases, its inertia decreases so its angular velocity will increase
