"Speed" is a scalar; "velocity" is a vector.
velocity is a vector and speed is a scalar.
Velocity is a vector. Speed is defined as the scalar component of velocity, so it's not a vector.
The size of the velocity vector is the speed.
Velocity is a vector Speed is a scaler
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.
No. If you need a vector, you call it a "velocity".
Direction. Velocity is a vector, speed is a scalar.
velocity, or velocity vector.
velocity is speed with direction; velocity is a vector and speed is a scalar
Velocity is the vector form of speed. It is the speed of an object in a specified direction.
the velocity vector
No. Velocity includes a direction vector, which speed does not have.
Velocity is defined as speed in a certain direction, or vector.
Speed is scalar (that is, without direction) and velocity is a vector (speed plus direction) by definition in physics.
Speed is not a vector quantity, because it has no direction. When you combine speed with a direction, then you have a vector, called "velocity".
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.
Velocity is an indication of a speed, including a direction. It is a vector because that is how a vector is defined (a magnitude, including a direction).
Velocity is a vector. It is characterized by its magnitude and direction. The magnitude of the velocity vector is the speed. Speed is only a numerical value, it has no direction. Velocity vector can be broken down into its components while speed, being just a number, has no components.
Velocity is a vector. The magnitude of the velocity - its absolute value - is its speed.
As used in physics, the two are different. Speed is a scalar, velocity a vector.
Why? Because that's the way speed and velocity are defined.
Yes. Speed is a scalar, while velocity is a vector.
Velocity is a vector (speed and direction). Speed alone is a scalar.
Speed is a scalar, velocity is a vector. In other words, when the direction of the speed is relevant, it is called a velocity.
