Question

A race car drives one lap around a race track that is 500 meters in length. What is the driver's displacement at the end of the lap?

Answer 1

Answer:

zero

Explanation:

Displacement is a vector, meaning that the direction is  very important. Displacement is the distance from the starting point to wherever the object is. So a car that does a 500 m lap will have covered 500 m in distance but displacement is zero because, having come back to the starting point, the distance between the starting point and where the object is, is zero.
