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.
"Speed" is a scalar; "velocity" is a vector.
velocity is a vector and speed is a scalar.
velocity is a vector and speed is a scalar.
The size of the velocity vector is the speed.
Velocity is a vector Speed is a scaler
"Speed" is a scalar; "velocity" is a vector.
velocity is a vector and speed is a scalar.
velocity is a vector and speed is a scalar.
The size of the velocity vector is the speed.
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.
Velocity is a vector Speed is a scaler
All of those are vectors except 'speed'. Speed is the scalar magnitude of a velocity vector.
Direction. Velocity is a vector, speed is a scalar.
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.
Speed is scalar (that is, without direction) and velocity is a vector (speed plus direction) by definition in physics.
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.
