Answer 1

Answer on Question #41434 – Physics - Mechanics | Kinematics | Dynamics

The motion of a rigid object for which all its constituent particles undergo the same kind of displacement is referred to as --- motion

oscillatory

translational

random

rotational

Solution:

«If a body is moved from one position to another, and if the lines joining the initial and final points of each of the points of the body are a set of parallel straight lines of length $\ell$, so that the orientation of the body in space is unaltered, the displacement is called a translation parallel to the direction of the lines, through a distance $\ell$»

Thus, the correct answer is translational.

Answer: translational
