Question
Why do cricketers wear helmet and pads while playing? Is it related with physics?
✓

Answer

Helmet and pads used by cricketers protects the head, using principles of physics.
  1. The framing between the interior of the helmet and pads increases the time over which the impulse acts on the head resulting into reduction of force.
    (Impulse = force × time = constant)
  2. The pads spread the force applied by the ball over a wider area reducing pressure at a point.
