Velocity includes both speed and direction, so velocity will change when an object changes direction while maintaining it's speed. An example is a car at constant speed around a curve.
When the velocity of a moving object stays the same, it has a constant speed.
an acceleration of Zero, and a constant Inertia.
Velocity can change if the direction of motion changes while the speed remains constant. Velocity is a vector quantity that takes both magnitude (speed) and direction into account. So, if an object moves in a different direction while maintaining the same speed, its velocity will change.
Velocity is a vector quantity that includes both speed and direction. If the direction of motion changes while the speed remains constant, then the velocity will change. This can happen when an object moves in a circular path, for example.
For an object's speed to change (increase or decrease), the object must be accelerating. If there is an acceleration, there is a non-zero net force acting on the object.note: Velocity and speed are different. An object's velocity can change without the speed changing. Example of this is centripetal acceleration. The object's velocity changes directions, thus the velocity changes. The magnitude (or speed), however, stays the same (if only a radial acceleration is present).

Newton's First Law of Motion, also known as the Law of Inertia, states that an object at rest stays at rest and an object in motion continues in motion with the same speed and in the same direction unless acted upon by an external force.
Velocity is a vector (has a size and a direction) but speed is a scalar (just a number). The velocity is therefore given by the speed and the direction the speed is going. If you change the direction but continue at the same rate the velocity changes but the speed doesn't
If an object's mass stays constant but its momentum is changing, then its velocity must be changing as well. This implies that there is an external force acting on the object, causing its momentum (mass multiplied by velocity) to change. This concept is described by Newton's second law of motion, which states that the rate of change of an object's momentum is equal to the force applied to it.
That depends on the situation. If the object is moving freely in a vacuum, the speed stays the same. If an object is accelerating, the speed change depends in part, on the mass of the object.
