2. Hello my name is Timu and I am going to tell
you what aerodynamics is with vehicles.
But first here are some key words below just to see if you
know them or not. If you don’t know any of these words I
will explain what they mean. So once you know them keep
them in mind because I will quiz you at the end.

4. Here we have two types of vehicles. A truck
and a car. These will be my assistants.

Do you know witch one is more aerodynamic

5. Thats Wrong
The front of the truck is flat so the air just hits the
front of the truck so the wind fights against the
truck.

go

6. Thats Right!
The airflow goes over the car when it is driving
because it is shaped to go fast. If you look at the front
of the car it isn’t flat, it’s curved so it is more
aerodynamic.

7. This here is a dragster. These type of vehicles are made
for short but fast races and they are very aerodynamic.
Spoilers are the
piece on the back
of a dragster

They make the airflow
go down to stop the
dragster to lift
Dragsters Thrust very
fast so they also have a
parachute to stop it from
speeding on past the finish
line. That is called the
drag.

14. A dragster without a spoiler would slowly raise by
the second from its speed then tip backwards.
