Question

Plzz answer my questions fast its very urgent

Answer 1

6
No, distance can't be smaller than displacement.
7
Distance is equal to the displacement when an object travels along the straight path in one direction only.
8
No, it's not necessary because speed is a scalar quantity that is, it doesn't depend on direction.
9
Yes, it is necessary because velocity is a vector quantity therefore, direction will affect velocity.
Moreover there can be only two paths- straight or curved. And in a curved path the director motion at a point is the tangent to that point therefore, at every point direction changes.
THANKS.
HOPE THIS HELPS YOU.
