My name is kiara chambers and this is my project on how roller coasters can effect the human body. Enjoy.

2. How Roller Coasters Effect The
Human Body
 Introduction: My presentation will show
how riding roller coasters can affect the
human body in following areas:
 The Heart
 The Neck & Back
 The Mind

3. The G-Force Effect On The
 Definition: G force is the forceHeart a high speed object
created when
changes direction. The change of direction usually follows a curved
path.
 On a roller coaster G-forces constantly push and pull at our
bodies. If we go fast enough, the force of gravity can stop
the flow of blood to our brains and eyes, causing blackouts
or temporary blindness.
 The American Heart Association say's riding a roller coaster
can speed up the heart-rate in many individuals.
Researchers believe that the increased heart-rate is a
result of psychological stress, triggered by fear of the roller-
coaster, as well as the G-forces acting on the riders. For
most people, especially young people, an increased of the
heart-rate is not a problem. An increased heart rate can
lead to an irregular heartbeat. This can be dangerous for
those who, may or may not know that they have heart
problems which can cause them to have a heart attack if

5. Whiplash Injuries
 Because roller coaster rides can make
quick, and sudden movements, it can
cause spinal injuries known as whiplash in
some people. Typically, the effects of
whiplash don't show until maybe a day or
two after the person leaves the ride.
Whiplash injuries can cause pain in the
neck or back, as well as reduced
movement in the arms.

7. Psychological Effect
 For some people the very idea of getting on a
roller coaster can be very frightening . They
don’t know whether to go on the ride or not.
Even before the ride, this psychological
reaction has a physical side-effect, causing
people to sweat more than usual. Your heart
starts to beat faster, your bladder starts to take
control, and you have a feeling something bad
might happen.

8. So why do we do it?
 In spite of all the craziness, we ride
the roller coasters anyway because
we like it and its
