What else can I help you with?
Why do we say that velocity is a vector and speed is not a vector?
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.
Which is vector speed or velocity?
"Speed" is a scalar; "velocity" is a vector.
Why is velocity a vector but speed is not?
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.
Which is a vector quantity speed or velocity?
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.
What measures both speed and direction at the same time?
A vector quantity measures both speed and direction at the same time. Velocity is an example of a vector quantity, as it includes both the magnitude (speed) and the direction of an object's motion.
Is Speed is a vector quantitys?
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".
What are facts about speed?
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.
Why is velocity a vector but not a speed?
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.
Is speed a vector or a scaler?
Speed is a scalar .
Why do we say that velocity is a vector and speed is not a vector?
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.
How is velocity diffrent from 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.
Which is vector speed or velocity?
"Speed" is a scalar; "velocity" is a vector.
Why is velocity a vector but speed is not?
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.
How do you find speed given a vector?
Given a vector, speed is the magnitude of the velocity vector, |v|. Consider vector V= IVx + JVy + KVz the magnitude is |V| = ( Vx2 + Vy2 + Vz2)1/2
Which is a vector quantity speed or velocity?
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.
Is 55 miles per hour a vector?
No. It is a speed (a scalar) but not a velocity (a vector).
Which of these references a velocity (not speed)?
I would say vector
