Rectilinear motion: A particle moving along a straight-line is said to undergo rectilinear motion. For example, motion of a train on track, freely falling body under gravity etc.

The perfect mechanism for this motion is a rolling wheel that turns on its axle to move along its trajectory. Assuming no slippage, its relative motion with the contact surface is zero.

This article is continuation of Class 11th Physics Notes: Motion in a Straight Line (Part – I & Part – II) where basic concepts like Rectilinear motion, Frame of Reference, Path Length ...
