Question

Under what condition is the displacement of an object equal to distance travelled by the object?

Answer 1

Answer:

Explanation:

Distance covered is only ever equal to the magnitude of displacement if the direction component of the object's velocity is constant. That is, as long as the object travels in a straight line, without doubling back, will distance = displacement.

Hope it helps you.

Answer 2

Answer:

Explanation:

Displacement is the shortest distance between initial position and final position whereas distance is the length of the path travelled between these two positions.

Thus, distance travelled between any 2 fixed points can vary depending upon the path taken whereas displacement will be fixed as the shortest distance between any 2 points is given by the length of straight line between these 2 points (positions).

So, out of different paths, when the object takes straight path to travel, i.e., when the object travels in a straight line without changing its direction, then the path length will be the shortest and distance covered will be equal to the magnitude of displacement.
