Is Translational motion and Rectilinear motion same?

Dear Student,

They are quite similar. Rectilinear motion comes under the category of translatory motion.

A motion in which the body as a whole moves from one place to another with respect to a mean position. In this motion, direction of motion of all the particles of a rigid body are in same direction and having same velocities. For example :

• The motion of the block sliding down an inclined plane is translational motion.

• All the particles of the body move together i.e, they have the same velocity at any instant of time

Straight line motion of a body is called rectilinear motion.An ant crawling on table is an example of rectilinear motion.
