The document traces important developments in transportation from 3500 BC to the present. It notes that the wheel was invented around 3500 BC and was fundamental to later inventions like vehicles and clocks. Important early transportation methods included boats, carts, and horses. Major innovations included hot air balloons in 1783, steamboats in 1787, trains in the early 1800s, cars in 1862-1903, motorcycles in 1867, and airplanes in 1903. Space exploration milestones were Sputnik 1 in 1957, the first manned moon mission in 1969, and the first space shuttle in 1981. Cars are now the most widely used transportation globally.

4. The wheel was invented around 3,500 BC.
It was a major milestone in the history of human
development.
The wheel can be used for many purposes like making toys,
vehicles, clocks etc.
The wheel is the base for most of the inventions made by
humans.

5. After the wheel was invented people started using carts
to transport goods and chariots or bullock carts to travel.
Boats with oars were also invented to travel in water
bodies.
Horses were also popular. They later became very
common during the medieval period.

6. The hot air balloon was invented in 1783.
It was the first machine to travel through air.
The steam boat which was invented in 1787 was a
milestone in the evolution of transportation.
Many steam locomotives were made during this
period. They were also used on roads.
The first car was made in 1862. They became popular
rapidly in the western countries.
This was followed by the invention of the motorcycle
in 1867.
The modern cycle was invented in 1790.

7. The steam boat was invented in 1787.
It started the industrial revolution as the steam
engine spread widely and became popular.
In the steam engine smoke, which pushes a wheel
above it, is released.
This wheel is connected to the underwater wheels
which push the boat forward.
Steam boats were mainly used to
transport goods

8. The Wright brothers invented and flew the 1st airplane
in 1903.
The helicopter was invented in 1940. Although it is
slower than airplanes it has the advantage of better
control.
The first manned space mission to moon- Apollo 11,
landed on the moon on July 20, 1969.
After this many space shuttles were sent in space.

9. Cars are the most popular means of transport in the world.
The greatest advancements in cars were made by Henry Ford.
Cars are powered by liquid fuel-either gasoline or diesel.
Cars are also very popular in motor sports like f-1 and f-2.
