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 GG-Force Effect On The Heart
 Definition: force is the force created when a high speed object 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 they ride a roller coaster.

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
