Question

What do you mean by pure translational motion of a rigid body ?​

Answer 1

Answer:

A Rigid body where each point of this rigid body they have exactly same displacement, same velocity, same acceleration. ... Therefore, cases of pure translation a rigid body may be considered to be concentrated in a particle with the same displacement parameters, velocities and accelerations. This is pure translation.

Answer 2

★ In this type of motion access attached to the rigid body remains parallel to its initial orientation.

★ Which means velocity and acceleration of all the particles present on the rigid body will be equal to each other at any instant of time.
