Displacement vector equals the change in position vector over time interval (3-6)

Question 1 of 4

Question

To calculate the displacement vector, subtract the earlier value from the later value (just as for motion in a straight line).

Review

This vector points from the object’s position at $t_1$ to its position at $t_2$ , and is the difference between the object’s position vector $\boldsymbol{\vec{r_2}}$ at $t_2$ and its position vector $\vec{r_1}$ at $t_1$ .
