Question

How can be explain pressure due to the force of gravity?

Answer 1

Respuesta:

¿Cómo puede explicar la presión debida a la fuerza de gravedad?

Explicación:

If you tried to use a hammer to drive a bowling pin to a wall, probably nothing would happen except that people would stop lending you their bowling pins. However, if you used a hammer to drive a nail with the same force, it is more likely to go into the wall. This shows that sometimes it is not enough just to know the magnitude of the force: you also have to know how that force is distributed on the impact surface. For the nail, all the force between the wall and the nail is concentrated in the small area of its sharp point. For the bowling pin, the area in contact with the wall is much larger and the force is much less concentrated.
