Question 8 — During a high jump - Questions at the end of the chapter - Chapter 6 - How Forces Affect Motion (Exploration)

Last updated at June 28, 2026 by

During a high jump event, a landing mat or sand bed is placed for the athlete to fall upon (Fig. 6.39). Explain the reason behind it.
View Answer Hide Answer

The soft mat or sand increases the time over which the athlete's body stops on landing. A longer stopping time means a smaller acceleration, and so a smaller force acts on the athlete (F = ma), reducing the risk of injury.
