10.Distance is the Actual length of the path travelled by the object. Displacement is shorterest distance between initial and final position of the object. It is a scalar quantity. It is a vector quantity.

Answer 2

Answer:

Scalar : A scalar quantity only has a magnitude & it can be represented by a number only. A scalar does not have any direction. The addition of scalars follows the generic rules of the addition of number.

Distance :Distance is the total movement of an object without any regard to direction. We can define distance as to how much ground an object has covered despite its starting or ending point.
