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".
"Velocity" is a vector quantity. This also applies to instantaneous velocity. If you want the scalar quantity, you talk about "speed".
Velocity is a vector.Its magnitude is called 'speed'.
velocity is a vector quantity because it`s formula is displacement by time and displacement has a particular direction. that`s why velocity is a vector quantity but speed is a scalar quantity
Yes, velocity is a vector quantity since it can be defined by both magnitude and direction unlike speed.
Velocity has a direction while speed doesn't. This is why we say that velocity is a vector quantity and speed a scalar quantity.
Speed = distance/ time Velocity = displacement / time distance is scalar and displacement is vector
Speed is only a magnitude (single value) while velocity is both magnitude and direction. Direction is a vector.
Speed is a scalar quantity because it has magnitude but not direction, velocity is a vector quantity because it has magnitude and direction.
Why? Because that's the way speed and velocity are defined.
Speed is a scalar quantity as it has magnitude, and no direction. Velocity, on the other hand, is a vector quantity as it has both magnitude and direction.
Since speed is the magnitude component of the vector quantity of velocity, of course when speed changes velocity also changes. Speed is a one dimensional scalar quantity. Velocity is a three dimensional vector quantity describing both speed and direction of motion.
In physics:If you talk about speed, that refers to a scalar quantity.If you talk about velocity, that refers to a vector quantity.
A vector has magnitude AND direction, a scalar just has magnitude.
A vector quantity not only has a size, it also has a direction. Velocity is a vector quantity. "30 mph north" and "30 mph east" are different velocities. "Speed" is a part of velocity ... its size alone, without its direction, so speed is not a vector quantity.
Speed is what it is: speed. Velocity is speed in a given direction, a vector quantity.
Because it is defined that way. In common language, the words "speed" and "velocity" are used interchangeably. But in physics, if a vector quantity is desired, the word "velocity" is used; for a scalar quantity, the word "speed" is used.
Momentum is a vector quantity. We know that momentum is the product of mass and velocity, and velocity has direction. That makes velocity a vector quantity. And the product of a scalar quantity and a vector quantity is a vector quantity.
No, constant velocity implies constant speed. But velocity can change even when speed remains constant, since speed is a scalar quantity but velocity is a vector quantity.

Yes, velocity is a vector quantity.
Speed and velocity are similar because they are both measures of quantity that involve motion. They differ because speed is a scalar quantity while velocity is a vector.
Velocity refers to both speed and direction. A vector refers to both magnitude (the speed in this case) and a direction. Speed without reference to a direction is a scalar, a magnitude without direction.
velocity being a vector quantity has both direction and magnitude but speed being a scalar quantity has only magnitude.
