SUMMARY

Displacement and velocity are vector quantities that can indeed be negative, indicating movement in the opposite direction. In one-dimensional motion, negative displacement occurs when an object returns to its original position and then moves backward. Similarly, negative velocity is observed when an object moves in reverse, such as a car moving backward. This understanding is crucial for accurately interpreting motion in physics.

how displacement and velocity can be negative.
 
Mathematics news on Phys.org
Both displacement and velocity are vector quantities. When confined to one dimension, negative means going in the opposite direction from positive.
 
You can have a negative displacement if you go forward a certain distance, return to your original position and then go backward. You can have a negative velocity if you move backwards such as reverse in a car. Like mathman said its just the opposite direction.
