As far as we can tell, it doesn't.
Momentum is defined as (mass) times (velocity). There appear to be only two ways
in which momentum can decrease: either the mass has to magically evaporate, or
else the velocity has to decrease. Since mass conservation is a nearly fundamental
law of nature, that leaves us with velocity as the only way to change the momentum
of a moving body.
What else can I help you with?
Why an object will move if its velocity is constant?
If an object's velocity is constant, it will continue to move at the same speed and in the same direction due to Newton's first law of motion. Unless an external force is applied, the object will maintain its state of motion.
What will happen to the velocity of an object that increases its mass from 5 kg to 10 kg and maintains a momentum of 10 kgm slash s?
The velocity of the object will decrease proportionally to its increased mass in order to maintain its momentum of 10 kgm/s. The velocity will be halved, as the momentum needs to stay constant even when the mass doubles.
What is mometum?
momentum is an object's tendency to remain in motion, or to remain at rest. momentum can also be described as the product of the mass and velocity of an object. "an object at rest tends to stay at rest unless acted upon by an outside force"
If balanced forces act on a person what does that mean about their motion?
It means they stay still, or they move at constant velocity.It means they stay still, or they move at constant velocity.It means they stay still, or they move at constant velocity.It means they stay still, or they move at constant velocity.
Does velocity stay the same when speed and direction stay the same?
Yes, velocity remains the same when both speed and direction remain constant. Velocity is a vector quantity that includes both speed and direction, so as long as both are unchanged, the velocity will remain constant.

Why must a force be exerted in an object ti change its velocity?
We know that that is the way our Universe works; WHY the Universe was designed that way, or why it happens to be that way, is normally not known.In this case, with a different law for velocity, lots of the physics we know would be drastically different - for example, conservation of energy, conservation of momentum, and conservation of angular momentum could all be violated.

Yes, velocity remains the same when both speed and direction remain constant. Velocity is a vector quantity that includes both speed and direction, so as long as both are unchanged, the velocity will remain constant.
Describe the momentum of objects at rest?
Measured in the frame of reference in which the object is at rest; zero since momentum is mass times velocity. Note that momentum is zero but inertia is not.
What are the condition for an object to stay at rest the moving at constant velocity?
The condition for an object to stay at rest or if moving, moving at a constant velocity is that the sum of forces acting on the object be zero or that no force acts on the object.
What are conditions for an object to stay at rest to keep moving at constant velocity?
The condition for an object to stay at rest or if moving, moving at a constant velocity is that the sum of forces acting on the object be zero or that no force acts on the object.
What are the condition for an object to stay at rest to keep moving-at constant velocity?
The condition for an object to stay at rest or if moving, moving at a constant velocity is that the sum of forces acting on the object be zero or that no force acts on the object.
What are the conditions for an object to stay at rest to keep moving at constant velocity?
The condition for an object to stay at rest or if moving, moving at a constant velocity is that the sum of forces acting on the object be zero or that no force acts on the object.
What does Newton's first law?
a body at rest will stay at rest unless acted on by an unbalanced force; also a body in motion at constant velocity will stay in motion at constant velocity unless acted on by an unbalanced force
