Consider two children, say \(A\) and \(B\). Let us say they weigh the same. Both start climbing up a rope separately. Both reach a height of \(8\) \(m\). Let us say \(A\) takes \(15\) \(s\) while \(B\) takes \(20\) \(s\) to accomplish the task.
  • What is the work done by each?
  • The work done is the same. However, A has taken less time than B to do the work.
  • Who has done more work in a given time, say in \(1\ s\)?
The formula to calculate the work done is,
 
Work done per unit time by the children \(A\) is  children \(B\).
