Physics to the means of transport

And the ways to travel for the man kind is by the land, water, air and outer space. The technology to travel by the land since the past exists the sled (trenó in Portuguese also is the name of something that exists in physics, like a principle only had the notion like you want an experiment you use the trenó like a rocket car you use a trenó and not wheels) and the wheal, the fact is what will be the empuxo (thrust), an animal or a machine.

And for the air and water, so you had to know about aerodynamics and hydrostatics.

So to the man travel by the land in the past don’t have physics involve, but have nowadays to make the transportation even more perfect, secure and fast; but for the water and air had physics involve.

To the water how to make something heavy float, how to make something heavier than the water float if you are thinking in something like a boat, until that day you can swimming (for who don’t know learn), or still how to make something with air sink if you are thinking in something like a submarine, so you had to study hydrostatic, can you imagine that the invention of the submarine was fast because already had the hydrostatic, and to confect only had to study something that was based in experiments that exists that the experimental submarine already exists and ground the theory that was used in the ones of the modernity. Experimental travel that is succeed don’t make a means of transportation because isn’t make in large scale, is almost like art and you are looking for art craft.

So about the air you have to know about the aerodynamics how to make something heavier than the air fly or float, the principles of the aerodynamics are very old and was for many persons to read, the genius is you construct the machine, you see the persons are looking for something with heavy machine, or something that was repeat a lot, you aren’t looking for a flying apparatus but for a land of flying apparatus. So was there the principles the genius was to make the apparatus that fly, machines are heavy, a flying apparatus is so much more possible if you think that physics can make it fly without need nothing (machine) but the principles of physics apply, this also is technology like the materials are, knowledge is power and you can fly. You see if aren’t a physician you know would get attached to the draw of the apparatus and not of the principles, understand had many designs for the apparatus the principles could be used in any kind of design, something is principle and other is design, who make a design that fly isn’t the owner of the principles the person only achieve to make a good design.

And more the studies of the air and water make more precise machines that had nothing about with the travel that are the machines that are pneumatics and hydraulics, pneumatics is something that had air inside, like a air bomb or air pump, hydraulics is something that had water inside to the engineering work more smooth.
