The types of motion which a cylindrical drum rolling down an inclined plane undergoes are
Answer Details
A cylindrical drum rolling down an inclined plane undergoes rotational and translational motion.
Rotational motion refers to the spinning motion around its own axis, which the drum exhibits while rolling down the inclined plane. Translational motion refers to the linear motion of the center of mass of the drum, which moves along the inclined plane.
Therefore, the correct answer is "rotational and translational."
