Question

A circular track is made on which an athlete has to cover three rounds to complete a 1000m run. During the run find the distance and magnitude of displacement of the athlete​

Answer 1

Answer:

distance= 3000m

displacement=0

Answer 2

Answer:

Distance = 1000m     Displacement = 0

The main difference between distance and displacement is that the distance is the actual physical length between two points while displacement is the length of the shortest route between these two points.

In  this case the object returns to its starting point hence the displacement will be zero.

Distance is scalar quantity and can never have 0 value on the other hand displacement is vector quantity and can be 0.
