Question

During a high jump event, a landing mat or sand bed is placed for the athlete to fall upon (Fig.). Explain the reason behind it.

Answer 1

A landing mat or sand bed increases the time taken for the athlete to come to a stop after landing. This increase in time reduces the magnitude of acceleration. According to Newton’s Second Law of Motion (F = ma), a smaller acceleration results in a smaller impact force. Therefore, the mat or sand bed reduces the force acting on the athlete and helps prevent injuries.
