The video tutorial explains the concept of relative motion using a toy car and a moving piece of paper. It introduces a problem where the car's velocity is given relative to the paper, which itself is moving relative to the Earth. The tutorial visualizes the problem, discusses vector addition, and solves the problem by breaking down the vectors into components. It concludes with calculating the resultant velocity's magnitude and direction using trigonometry.
