The total work done by carrying two buckets in one trip or all in one trip is the same as the energy change in the six buckets is same in both cases. Either way buckets will gain the same increase in potential energy so work done is change.
But you will feel more exhausted when you carry all six once and will feel more comfortable when carrying 2 at a round.
This is not because you will doing different amount of work but due to drawing out same amount of work in different ranges of time.
When carrying 2 at a round you draw same amount of energy in lesser time so body can easily support the energy draining out than in the other case of carrying all 6 buckets once.
<span>Following both the statements are true: Some Defined it by "Supported by most but not all". Some defined it by this statement: </span>"Not studied by many scientists"
