Even though velocity combines both magnitude and direction, velocity is considered a vector quantity. Rest as well as motion are still considered relative terms because they depend just on the observer's point of view
An object changing its position having regard to time has been referred to as motion.
The speed where something travels in a specific direction would be known as its velocity.
(a) Rest as well as motion are still considered relative terms because they depend just on the observer's point of view. Even if an observer is moving while remaining stationary with their own framework of reference, this is possible.
(b) A body falls under the gravitational force of gravity in free fall, which beliefs to be constant near the earth. The body falls as a result of constant acceleration. Speed but also velocity would change because acceleration becomes non-zero.
(c) Displacement contains both magnitudes as well as direction, but distance just contains magnitude or any motion would result in the distance it travels, so it is possible to even have zero displacements with nonzero distance. Zero distance and nonzero displacement are not compatible in a one-dimensional motion.
(d) Speed just has magnitude and no direction, it represents a scalar quantity. Speed only reveals the distance covered by such a body in a given amount of time; it does not reveal its direction of motion. It has a scalar quantity mostly as a a result.
(e) Even though velocity combines both magnitude and direction, velocity is considered a vector quantity.
