Yes, always. Velocity is a vector, meaning it has both a magnitude and a direction. You must account for the direction.
Speed is the magnitude of velocity and has no direction.
Velocity is acceleration and direction put together. The velocity of something changes if either acceleration or direction changes. Speed is just the average MPH measure. Velocity is not acceleration and direction put together. In that kind of description, velocity is is speed and direction put together. Velocity is a vector, whose size is the speed.
The direction of instantaneous acceleration is in the direction of the change in velocity at that moment. If the velocity is increasing, the acceleration is in the same direction as the velocity. If the velocity is decreasing, the acceleration is in the opposite direction of the velocity.
The velocity direction of an object indicates the direction in which it is moving. The motion of an object is determined by both its velocity magnitude (speed) and its velocity direction. The velocity direction influences the path the object takes as it moves.
Acceleration determines the direction of velocity. Velocity is a vector quantity that includes speed and direction, while acceleration is the rate of change of velocity. If an object is accelerating, its velocity is changing, which means its direction is also changing.
Momentum is a vector quantity, meaning it has both magnitude and direction. The direction of momentum is the same as the direction of the velocity of an object. This is because momentum is defined as the product of an object's mass and velocity, and velocity has a direction.

the velocity of an object is the size of the speed/magnitude plus the direction it is going in
Speed in a given direction is velocity.
Momentum is mass x velocity; velocity has a direction, therefore momentum has a direction.Momentum is mass x velocity; velocity has a direction, therefore momentum has a direction.Momentum is mass x velocity; velocity has a direction, therefore momentum has a direction.Momentum is mass x velocity; velocity has a direction, therefore momentum has a direction.
You need to know its direction. Put that togetherwith the speed, and you'll have the velocity.
The direction of instantaneous acceleration is in the direction of the change in velocity at that moment. If the velocity is increasing, the acceleration is in the same direction as the velocity. If the velocity is decreasing, the acceleration is in the opposite direction of the velocity.
Speed in a given direction is called velocity.
The velocity direction of an object indicates the direction in which it is moving. The motion of an object is determined by both its velocity magnitude (speed) and its velocity direction. The velocity direction influences the path the object takes as it moves.
There are several definitions. not just one. Average velocity in a direction = Average displacement (distance) in that direction/time Instantaneous velocity in a direction = derivative of displacement in that direction with respect to time Average velocity in a direction = Initial velocity in that direction + Average acceleration in that direction * time Instantaneous velocity in a direction = Definite integral of acceleration in that direction with respect to time, with initial velocity at t = 0 Then there are others in which time is eliminated.
Acceleration determines the direction of velocity. Velocity is a vector quantity that includes speed and direction, while acceleration is the rate of change of velocity. If an object is accelerating, its velocity is changing, which means its direction is also changing.
Momentum is a vector quantity, meaning it has both magnitude and direction. The direction of momentum is the same as the direction of the velocity of an object. This is because momentum is defined as the product of an object's mass and velocity, and velocity has a direction.
Velocity describes both the speed and direction an object is moving.
