Question

position vector of the particle is​

Answer 1

Explanation:

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. ... The position r and the velocity v of a moving particle of mass m. The point O denotes the origin, and r0 denotes the distance between the line of motion and the origin.

Answer 2

Answer:

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.
