Question

The numerical ratio of displacement to distance for a moving object is:

• A. Always less than 1
• B. Always equal to 1
• C. Always more than 1
• D. Equal or less than 1.

Answer 1

The correct option is D Equal or less than 1.

Displacement is the shortest length between the starting and the end pointing of a journey, whereas the distance is the actual length of the path travelled. Hence, the distance will be always equal to displacement or greater than displacement. So, the ratio of displacement to distance will be always less than or equal to 1, since denominator (distance) is either greater than or equal to the numerator (displacement).
