2  Since the end of the age of sail a ship has been any large buoyant marine vessel. Ships are generally distinguished from boats based on size and cargo or passenger capacity. Ships are used on lakes, seas, and rivers for a variety of activities, such as the transport of people or goods, fishing, entertainment, public safety, and warfare. Historically, a "ship" was a vessel with sails rigged in a specific manner.age of sailbuoyantmarine vesselboatslakesseasriverstransport of peoplegoodsfishing entertainmentpublic safetywarfare  Ships were key in history's great explorations and scientific and technological development. Navigators such as Zheng He spread such inventions as the compass and gunpowder. Ships have been used for such purposes as colonization and the slave trade, and have served scientific, cultural, and humanitarian needs. New crops that had come from the Americas via the European seafarers in the 16th century significantly contributed to the world's population growth.Zheng Hecompassgunpowdercolonizationslave tradeNew crops  The first ship was invented by the great egyptians around 3150 BC.

3  A motorcycle (also called a motorbike, bike, or cycle) is a single- track, two-wheeled [2] motor vehicle. Motorcycles vary considerably depending on the task for which they are designed, such as long distance travel, navigating congested urban traffic, cruising, sport and racing, or off-road conditions.single- track [2]motor vehiclelong distancecongested urban trafficcruisingsportracingoff-road  Motorcycles are one of the most affordable forms of motorised transport in many parts of the world and, for most of the world's population, they are also the most common type of motor vehicle.There are around 200 million motorcycles (including mopeds, motor scooters and other powered two and three-wheelers) in use worldwide, [6] or about 33 motorcycles per 1000 people.

4  A bus is a road vehicle designed to carrypassengers. Buses can have a capacity as high as 300 passengers. road vehiclepassengers  Buses may be used for scheduled bus transport, scheduled coach transport, school transport, private hire, tourism; promotional buses may be used for political campaigns and others are privately operated for a wide range of purposes.scheduled bus transportscheduled coach transportschool transporttourismpolitical campaigns  Horse drawn buses were used from 1820, followed by steam buses in the 1830 and electrictrolleybuses in 1882. The first buses powered by internal combustion engines were used 1895 and this is still the most common power source. Recently there has been growing interest in hybrid electric buses, fuel cell buses, electric buses as well as ones powered by compressed natural gas or bio-diesel.

5  A rocket or rocket vehicle is a missile, spacecraft, aircraft or other vehicle which obtains thrustfrom a rocket engine. In all rockets, the exhaust is formed entirely from propellants carried within the rocket before use. missilespacecraftaircraftvehiclethrustrocket enginepropellants  Rockets for military and recreational uses date back to at least 13th century China. Significant scientific, interplanetary and industrial use did not occur until the 20th century, when rocketry was the enabling technology of the Space Age, including setting foot on the moon.ChinaSpace Agesetting foot on the moon  Rockets are used for fireworks, weaponry, ejection seats, launch vehicles for artificial satellites,human spaceflight and space exploration. While comparatively inefficient for low speed use, they are very lightweight and powerful, capable of generating large accelerations and of attainingextremely high speeds with reasonable efficiency.fireworksweaponryejection seatslaunch vehiclesartificial satelliteshuman spaceflightspace explorationextremely high speeds

6  An automobile, autocar, motor car or car is a wheeled motor vehicle used for transportingpassengers, which also carries its own engine or motor. Most definitions of the term specify that automobiles are designed to run primarily on roads, to have seating for one to eight people, to typically have four wheels, and to be constructed principally for the transport of people rather than goods. [wheeledmotor vehicletransportingpassengerstransport  The term motorcar has also been used in the context of electrified rail systems to denote a car which functions as a small locomotive but also provides space for passengers and baggage. These locomotive cars were often used on suburban routes by both interurban and intercity railroad systems.
