A force, or several forces that don't add up to zero, acting on the object.
The change in an object's velocity is determined by its acceleration. If the object's acceleration is positive, its velocity increases; if it is negative, the velocity decreases. The larger the acceleration, the quicker the change in velocity will be.
Objects move when their balance is changed.
A change in an objects velocity is called acceleration. Velocity is defined as an objects speed of travel AND its direction of travel. Acceleration can change only an objects speed, only its direction or both. If there is no acceleration acting on the object, then the velocity remains constant.
A change in velocity can be caused by forces acting on an object. These forces can be due to interactions with other objects, such as a push or a pull, or due to internal processes like propulsion systems. Changes in velocity can also occur due to changes in direction, such as when an object turns.
Gravity changes velocity because it accelerates objects towards the Earth at a rate of 9.81 m/s^2. As objects fall, their velocity increases due to this gravitational acceleration. Conversely, when objects move against gravity, such as when thrown upwards, gravity decreases their velocity until they eventually stop and fall back down.

Velocity is a change in an object's motion OR direction of motion.

momentum is caused by inertia. all objects have inertia, which means if they are moving at a certain velocity or are at rest they will continue to move at that velocity or remain at rest unless acted on by a force. Objects of more mass have greater inertia, so the amount of momentum is equal to the product of an objects mass and the magnitude of its velocity.

Gravity changes velocity because it accelerates objects towards the Earth at a rate of 9.81 m/s^2. As objects fall, their velocity increases due to this gravitational acceleration. Conversely, when objects move against gravity, such as when thrown upwards, gravity decreases their velocity until they eventually stop and fall back down.
In all cases acceleration.
uniform motion
Acceleration is an object's change in velocity divided by its change in time. So: acceleration=(final velocity - initial velocity)/(final time - initial time)
