SUMMARY
The expression for the velocity of a car in vector form is defined as v = 63i + 0j + 0k, indicating motion solely in the x-direction. The discussion highlights confusion regarding the distinction between velocity and position vectors, emphasizing the need for clarity in problem statements. The position vector is represented as ##\vec{r}=r_i\cdot i +0j+0k##, where ##r_i## denotes the initial position along the x-axis. The use of unit vectors i, j, and k is essential for representing motion in three-dimensional space.
