Question
When does a man exert more pressure on the floor : while standing or while walking?
✓
Answer
The force acting per unit area is called pressure exerted by an object. It is given by $: P = \frac{ F }{ A }$
Pressure is inversely proportional to the area of the cross-section. While walking, the area that is in touch with floor is more, so it will exert less pressure.
On the other hand, while standing, the area in touch is less. So, it will exert more pressure.
Hence, while standing a man will exert more pressure.
