The magnitude of the velocity is always equal to the speed. But velocity is a vector quantity (has a magnitude and direction) while speed is just a scalar quantity (only magnitude). So velocity and speed are never equal.
-- The magnitude of acceleration is equal to the time rate of change of speed. -- The magnitude of acceleration is equal to the time rate of change of the magnitude of velocity. -- Acceleration and velocity are both vectors.
The magnitude of average velocity of an object equal to its average speed if that object is moving with CONSTANT velocity.
Velocity is a vector. The magnitude of the velocity - its absolute value - is its speed.
the velocity vector
Velocity is equal to the change in distance divided by the change in time. Speed is the magnitude of velocity
That is the case when you are talking about instantaneous speed and velocity - or when the velocity is constant. In the case of an average speed and velocity, this relation does not hold.
Speed is equal to the magnitude of velocity almost always. Speed is total distance / total time no matter which way the distance goes. Velocity is the distance from a starting point divided by total time.
speed (magnitude of velocity)
Magnitude of velocity is called 'speed'.
Velocity has magnitude and direction and speed only has magnitude.
The magnitude(the value). Speed is only magnitude Velocity is magnitude & direction
