Question

distinguish between displacement and path length​

Answer 1

Displacement:

• It is the length between the initial position and final position of a body.
• It is a vector quantity.
• It means , it has both magnitude as well as direction.
• For example, The displacement in one complete rotation on a circular track is Zero.
• It is beacuse the body reached the initial point again, making its final position.

Path Length:

• It is the total length of the path a body has travelled.
• It doesn't have direction.
• It has only magnitude.
• Thus, it's a scalar quantity.
• For example, The path Length in one complete rotation on a circular track is 2πr, where r is the radius of the circular track.

Answer 2

$Answer$

______________________________________

Path Length :

•Path length is a scalar quantity.

•The distance is depend on the path.

•It is not depend on magnitude.

•It can have only positive values.

•It can be measured in a straight path.

Displacement :

•It is the length between two points.

•It is a vector quantity depend on magnitude and direction.

•Displacent of a body can be zero (0).

•Displacement It is indicated with an arrow.

•Displacement can be measured in a straight path.
