When it either accelerates or decelerates
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.
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.
Objects with greater mass resist changes in velocity more than light objects. Additionally, objects with higher inertia or momentum also resist changes in velocity. Friction and air resistance can also act to resist changes in velocity.
To change an object's velocity, you need to apply a force to it. The force will cause the object to accelerate, thus changing its velocity. The magnitude and direction of the force will determine the extent and direction of the velocity change.
Yes, impulse is equal to the change in momentum of an object, which can be calculated as the mass of the object multiplied by the change in velocity. So, impulse is related to the change in velocity of an object.
Velocity is a change in an object's motion OR direction of motion.

either resistance or inertia
force
Acceleration is an object's change in velocity divided by its change in time. So: acceleration=(final velocity - initial velocity)/(final time - initial time)
In all cases acceleration.

Objects with greater mass resist changes in velocity more than light objects. Additionally, objects with higher inertia or momentum also resist changes in velocity. Friction and air resistance can also act to resist changes in velocity.
