Velocity is a vector because it has both magnitude (speed) and direction. Speed, on the other hand, is a scalar quantity that only has magnitude. Vector quantities require both magnitude and direction to be fully described.
"Speed" is a scalar; "velocity" is a vector.
The result of subtracting one velocity vector from another velocity vector is a new velocity vector. This new vector represents the difference in speed and direction between the two original velocity vectors.
Velocity is a vector quantity because it includes both the speed of an object and its direction of motion. Speed is a scalar quantity because it only represents the magnitude of motion without direction.
Acceleration and velocity are vector quantities because they have both magnitude and direction. Speed and temperature are scalar quantities because they only have magnitude.
Speed is a scalar quantity that refers to how fast an object is moving, whereas velocity is a vector quantity that refers to both the speed and direction of an object's motion. Speed is the magnitude of velocity.
I would say vector
Velocity is a vector, and so it has two components -- magnitude (speed) and direction. Speed is a scalar, and it is the magnitude of velocity, a vector.
Direction. Velocity is a vector, speed is a scalar.
"Speed" is a scalar; "velocity" is a vector.
Velocity is the vector form of speed. It is the speed of an object in a specified direction.
Speed is a scalar, velocity is a vector. That is to say, when you talk about "speed", the direction doesn't matter; when you talk about "velocity", it does. A velocity is only completely specified if you know the magnitude AND the direction.
Because velocity has a direction but speed does not. A vector has both a numerical value and a direction but a speed has only a numerical value and therefore it can't be represented by a vector.
The result of subtracting one velocity vector from another velocity vector is a new velocity vector. This new vector represents the difference in speed and direction between the two original velocity vectors.
speed is not a vector. Velocity is a vector. speed can also be used for angular velocity (which is a vector). Speed is sort of a catch all word that can cover all poorly defined velocities.
The main difference between speed and velocity involves direction. Velocity involves an object moving in a particular direction.
Velocity is defined as speed in a certain direction, or vector.
No. Velocity includes a direction vector, which speed does not have.
