Translational motion is a type of motion in which the same distance in a given time is covered by all parts of an object, for example, a car moving on the road and birds flying in the sky.
Translational motion is of two types: rectilinear and curvilinear.
In rectilinear motion, the object moves in a straight line, for example, a train moving on a straight track.
In curvilinear motion, the object moves along a curved path, for example, a car taking a turn.
