Q. 23 Why does a child feel more pain when she falls down on a hard cement floor than when she falls on the soft muddy ground in the garden? A
When a child falls on a cement floor, her body comes to rest instantly. As the time of stopping t decreases, therefore F increases, and hence, the child feels more pain.
When she falls on the soft muddy ground in the garden the time of stopping increases and hence, F decreases and she feels lesser pain.
