soil sustains us?
As we know each individual animal or object that is on our planet is made up of atoms, which in turn combine to form molecules, this in living bodies, constitute the generate tissues and cells becomes more complex systems that are coordinated each other to maintain life.
The atomic nucleus is the only part of matter that has significant mass and the set of all cores will be the total mass of the body subjected to the gravity of the place is transformed by weight.
remember that:
P = m. g
Weight is the product the mass of a body by the gravity of the place where the body is.
While the dough is a constant throughout the universe weight will vary depending on the point of the universe where the object is massive, as it depends on the severity.
When a person, animal or object is resting on the floor, the weight force exerted from the center of gravity down the floor with the solid structure is able to sustain necessary because in turn responds as a solid body line with Newton's third law or principle of action and reaction, generating a force equal and opposite to the weight Normal call holding and not allowing the body to sink.
In this case the principle of action and reaction occurs in each of the points of the object with the floor, table, receive normal responses in each of its legs, a person standing, in each of his feet. Normal call
force will be generated always there supporting the object on a solid floor.
When a body is supported on another solid than the floor in the area of \u200b\u200bsupport is generated by a reaction that causes the body on which it stands hold, that force is called contact force.
When the place of support is not necessary strong body structure will sink to find the normal reaction that is able to sustain it, such as in those that were invented inflatable structures for children to play in them taking advantage of the low resistance of the place. "Why
bodies float?
The liquid state, does not hold objects that are not light enough or offered a large contact surface to generate a thrust capable of sustaining.
Thrust is equal to the weight of liquid displaced when the body is submerged so that the larger the area that we offer to the liquid, the greater the amount of liquid displaced and the greater the driving force that sustains the body floating.
The boats are designed so that the part is immersed in water allows a large displacement and thus generate thrust to compensate for their weight and are let float.
The more dense the liquid, the greater the push to offer and easier it will float in salt water so you float better in fresh water. Small
