Answer 1

Question :-

A man carrying a bucket of water walks on a horizontal road with uniform velocity. What is the work done by him?

• Displacement :- Displacement is the shortest distance between the initial and final position. It is a vector quantity i.e. it has both magnitude and direction.

• Work Done :- Work done on an object is defined as the product of the magnitude of the force acting on the body and the displacement in the direction of the force.

Answer 2

$\huge\bold\orange {\mathfrak{answer:}}$

yes, when a man is carrying a bucket on a level road with uniform velocity work is not done. This is because work is not done when the force applied is perpendicular to the direction of displacement. when it is so it becomes 0 work done or no work.
