Depending on how you define it.
Momentum is always given positive units, but sometimes when considered in a relative view, it can be in a negative direction making the overall value negative too (while mass is always positive, velocity might be in a negative direction where e.g. two masses are moving in opposite directions).

∙ 14y agoYes , momentum is the tendency of a body to remain in motion even if the external force is removed, it is the product of mass and velocity
Wiki User
∙ 8y agoThe momentum will increase if the net force is in the direction of travel, but decrease if the net force is opposite direction as the object will slow down

What is the difference between positive and negative momentum?
The difference between positive and negative momentum is the direction that the object is going. Left and down are negative, right and up are positive. For example: if a ball is rolling to the left, it has a negative momentum.
Which can be described as in an isolated system momentum is always conserved?
Briefly, the only way for an object to change its momentum is by transferring momentum to another object - in other words, the other object will receive a change in momentum in the opposite direction.
How does friction affect interia?
Friction does not affect inertia, but it affects momentum. Momentum is the product of the mass of an object and its speed. Friction forces, if present, will always act to decrease the momentum of a moving object.
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.
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 is the difference between positive and negative momentum?
The difference between positive and negative momentum is the direction that the object is going. Left and down are negative, right and up are positive. For example: if a ball is rolling to the left, it has a negative momentum.
What direction will the momentum of an object always be going?
Away from the source.

Briefly, the only way for an object to change its momentum is by transferring momentum to another object - in other words, the other object will receive a change in momentum in the opposite direction.
Why is the momentum of a roller skater is not conserved?
The situation is not quite clear. Total momentum is always conserved, but momentum can be transferred from one object to another.

Friction does not affect inertia, but it affects momentum. Momentum is the product of the mass of an object and its speed. Friction forces, if present, will always act to decrease the momentum of a moving object.

No. Total momentum always remains constant. Therefore, if the momentum of one object decreases, the momentum of another must needs increase.
What forces act against momentum?
I don't see how anything can "act against momentum"; momentum is always conserved. If there is friction, the movement of the object will be slowed down; but in this case, momentum is transferred to the air, or whatever is slowing down the object in question. Total momentum will be conserved.
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.
How do you find the total momentum of 2 objects moving at the same speed in opposite directions?
(1) Decide on a direction that you will consider positive. (2) Calculate the momentum of the object that travels in the "positive" direction. (3) Calculate the momentum of the object that travels in the "negative" direction (the momentum should be negative). (4) Add both numbers algebraically.
The product of an object mass and velocity is called its What?
That's the object's linear momentum.
If you are parking facing downhill you should always turn your front wheels towards the sidewalk. The force of a moving object is called momentum. The momentum of an object is proportional to?
Momentum if the force that makes an object maintain it's movement, once it has speeded up and even when trying to stop. (Not to be confused with Inertia.)
