Question

Can the magnitude of displacement be equal to distance travelled by an object?

Answer 1

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.

OR

in case a body travels in a straight line path without any change in Direction

the minimum distance from initial position to final position is the same as total distance travelled

Answer 2

it can be equal and it cannot be equal also. if the distance is travel on a straight path then the magnitude of displacement and distance is same
