Today, work is not possible without proper transportation. To go from one place to another or to move something to a far off place we need some sort of transportation. Bus, trains, planes are various public transportation ways. Most of these are run by the government. For private uses, cars and motorbikes are present which can be bought from various dealers.
Transportation involves going from place to place. Since humans do not have the sufficient physical energy to do so on their own, they need the help of vehicles. A vehicle is an instrument or tool which is powered by an external force. These transportation vehicles can be moved either on land, float on the sea or fly in the air. Land ways of transport is preferably cheaper when compared to other means. It usually consists of devices with wheels which rotate and helps the vehicle to move. While most of these transportation vehicles need fuel to operate, some such as bicycles are manually powered.
Common land transportation includes bikes, cars, buses and trains. While some of these can carry only a few people, others are capable of transporting large number of people. Another way of transportation is water ways. Here devices are made to float on water and move forward with the help of a propellant. Water ways are useful to travel to places which cannot be reached by land ways. Islands are a common example for this. Boats and ships are water transportation vehicles.
For a high speed transport from one place to another, air ways are used. Airplanes and helicopters are used for this. These are powered by a very powerful engine capable of carrying the weights and still lift off. But the air ways are much costlier when compared to land and sea ways because of high speed transportation. It is normally used by people to travel to far off places like a different state or country.
