A bucket full of water is drawn up by a person. In this case the work done by gravitational force is

Work Done By Gravitational Forces

The sign of work done by a force on a body is important to understand .State carefully if the following quantities are positive or negative : (a) work done by a man in lifting a bucket out of a well by means of a rope tied to the bucket . (b) work done by gravitational force in the above case , (c ) work done by friction on a body siding down an inclined plane , (d ) workdone by an applied force on a body moving on a rough horizontal plane woth uniform velocity . (d) work done by the resistive force of air on a vibrating pendulum in bringing it to rest .
