Detailed explanation-1: -Velocity and acceleration vectors #rkv‑sv The velocity ⃗v and acceleration ⃗a are the first and second derivatives of the position vector ⃗r . Technically, this is the velocity and acceleration relative to the given origin, as discussed in detail in the sections on relative motion and frames.
Detailed explanation-2: -The average acceleration vector: is defined as the rate at which the velocity changes. It is in the direction of the change in velocity v. The instantaneous acceleration is the limit of the average acceleration as t approaches zero.
Detailed explanation-3: -The position vector r extends from the origin to the particle, while the velocity vector v points in the direction of the particle’s motion. Other variables, which are appropriate for describing a moving particle, can be defined in terms of these elementary variables.
Detailed explanation-4: -Quantities like force, velocity and acceleration are vectors. They have both a magnitude and a direction.
