Pak cricket captain's cover drive becomes a lesson in science textbooks

Pakistan's men's cricket team captain Babar Azam's cover drive has been a critics' favourite for a long time. It has now made it to the science textbook for ninth-standard kids as a lesson in kinetic energy.

The page is prescribed by the Federal Board of Education, Pakistan. It details the concept of kinetic energy as equal to half of an object's mass multiplied by the velocity squared measured in joules. Pakistani journalist Shiraz Hassan shared the page on Twitter.

The lesson is in the form of an example question: "Babar Azam has hit a cover drive by giving kinetic energy of 150j to the ball by his bat. (a) At what speed will the ball go to the boundary if the mass of the ball is 120 g? (b) How much kinetic energy a footballer must impart to a football of mass 450 g to make it move at this speed?"

The next two paragraphs in the book explain the concept further using a formula from the works of the German rationalist philosopher Gottfried Leibniz and the Swiss mathematician Johann Bernoulli.
