    - In rectilinear motion, the path traveled by a particle is a straight line.

    - The normal component of acceleration (aN) is zero when ρ is equal to infinity in the relation aN = (v2 / ρ).

    - The rectilinear motion is classified into two types such as:

    1) Uniform linear motion with constant velocity or zero acceleration
    2) Non uniform linear motion with variable velocity or non-zero acceleration.
