While catching a cricket ball the fielder lowers his hands backwards. Why?

उत्तर

  1. When the fielder lowers his hands backward, he increases the value of time of the collision and so retardation is decreased.
  2. Hence retarding force becomes lesser than before and the palm of the fielder is not hurt very much.
