Discuss the difference between translational motion and rotational motion.
The main difference between translational motion and rotational motion is that in translational motion change in relative speed is always zero but in case of rolling motion it is not equal to zero.
Case 1 when body is performing pure motion, then
V=rw, where w is angular velocity and relative speed is not zero
Case2 when body is sliding, then it is performing translational motion hence in this case relative velocity is zero.
