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.

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.
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.
What will the motion of the cart be like when there is no force at all?
he do not do any motion
Describe the momentum of objects at rest?
momentum is the tendency of an object to stay in motion or the force (energy) required to stop an objects motion. an object at rest (not moving) has no momentum.
Which of these is true of a person walking up the steps of a downward-moving escalator at a constant speed?
There are many things that could possibly be true of a person walking up the steps of a downward-moving escalator at a constant speed. This person could potentially stay in exactly the same place.

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.
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 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 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
What happens of there is no friction?
Objects would move with constant velocity or stay at rest.
When the velocity of a moving object stay the same it has?
an acceleration of Zero, and a constant Inertia.
Can a body have a constant velocity but varying speed?
No. If the speed varies, the body accelerates, and velocity cannot be constant.
What will the motion of the cart be like when there is no force at all?
he do not do any motion
