speed is a scalar quantity
yes.... A2: displacement is for of a number where a vector has direction. Kind of the difference in speed and velocity but the main difference in this is velocity can be negative.
Speed is a scalar quantity because it has magnitude but not direction, velocity is a vector quantity because it has magnitude and direction.
To make it easy, vector quantities have a direction aswell as a magnitude.While scalar quantities just have a magnitudeAn example of a scalar quantity is "Speed" and the vector quantity would be "Velocity"
A scalar quantity is just that, a quantity. Mass, speed, weight, height and the like. A vector quantity has direction. A mass moving South, 30 m/s straight up and all quantities having directionality included.
Velocity is a derived quantity. Speed is velocity without direction. Velocity is derived from distance and time.
Speed is what it is: speed. Velocity is speed in a given direction, a vector quantity.

Speed is a scalar quantity because it has magnitude but not direction, velocity is a vector quantity because it has magnitude and direction.
speed has only magnitude but no direction associate to it, if you consider velocity it consists of magnitude along with the direction. Hence speed is considered as a scalar quantity
A vector quantity refers to a physical quantity that has both magnitude and direction. Some examples of vector quantities include velocity (speed and direction), force (magnitude and direction), and displacement (distance and direction).

Scalar is a type of quantity which contains magnitude only and has no direction. For example: distance and speed
A scalar quantity is just that, a quantity. Mass, speed, weight, height and the like. A vector quantity has direction. A mass moving South, 30 m/s straight up and all quantities having directionality included.
Velocity is a derived quantity. Speed is velocity without direction. Velocity is derived from distance and time.
The quantity designated by the letter "c" is the speed of light
Velocity is a derived quantity. Speed is velocity without direction. Velocity is derived from distance and time.
A dimensionless quantity is one that has only a number, not a unit, and should therefore be the same in any system of units. This often happens when a quantity is the ratio of two measurements of the same kind. For example, the index of refraction can be considered the ratio of two speeds (the speed of light in a vacuum, and the speed of light in the corresponding substance); if both speeds are expressed in meters/second, when taking the ratio, the units disappear, and only a number without units - a "dimensionless" unit - remains. If you convert the speeds in this example to some other unit, for example kilometers per second, both speeds will be a thousand times less; but the ratio will still be the same.
