Rectilinear Motion Concepts

The video tutorial covers rectilinear motion, which is motion along a straight line. It explains three types of rectilinear motion: uniformly accelerated motion, uniform motion, and uniformly decelerated motion. In uniformly accelerated motion, the speed of an object increases at a constant rate. In uniform motion, the speed remains constant, and in uniformly decelerated motion, the speed decreases at a constant rate. The video uses a scooter as an example to illustrate these concepts, showing how speed changes over time in each type of motion.
