The Science of dancing

Introduction to Science of
dancing
 One reason why I
chose this sport
because I find that
dancing gives you a
lot of energy to your
body.
 Another reason why
I chose this sport
because when you
dance you move
muscle and sinew to
express the rhythms
of music, but also
concentration and
Potential Energy
 An example of
potential energy of
dancing is when
somebody moves or
jumps or falls or
explodes or breathes
or thinks or dances
or does anything, it's
because energy is
being transformed.
Kinetic Energy
 Kinetic energy is
motion, electrons,
atoms, molecules,
substances, and
objects. There is a
lot of example of
kinetic energy in
dancing, such as
when you here a
rhythm you jump, do
stepping, swing, and
turns.
Digestive System
 The digestive system
digests food to give our
body energy.Our body
needs to use energy to
chew the food and then
enzymes, the stomach,
liver, pancreas and
intestines work together
to give our body
nutrients. The digestive
system helps Dancing
give more energy to
move more your body.
Need to eat well in order
not to get dizzy or could
not be able to move your
body.
Respiratory System
 The Respiratory
System makes your
heart work fast and
makes your lungs
hard, they slowly
become larger and
can take in more air
each time you
inhale. In dancing
you need to take in
air in order to move
and breath to dance.
Circulatory System
 The circulatory system is
made up of the vessels
and the muscles that
help and control the flow
of the blood around the
body. In dancing you
need energy to move
around, spin, and jump
you even have to eat
well. With each
heartbeat, blood is sent
throughout our bodies,
carrying oxygen and
nutrients to all of our
cells.
Excretory System
The excretory
system functions
in ridding the
body of
nitrogenous and
other wastes.
Dancing need the
excretory system
to relax and cool
off their bodies.
Muscular System
 The Muscular System
controls movement.
Without muscles you
couldn't open your mouth,
speak, shake hands, walk,
talk, or move your food
through your digestive
system. Muscles are
attached to the skeleton
and move various parts of
the body. Dancers need
strong muscular to move
their legs, spin and jump
around.
Electric Energy
Electric energy is
when positive and
negative charges
make electricity.
The dancer need
electricity to
listen to music.
Energy Transformation
 Kinetic energy is
when you move a
lot.
Heat is almost
always produced in
energy
transformation.
Dancing can produce
heat energy by
moving around
causing the dancer
to get really hot.
Conserving Energy
Is good to save
energy to leave
and have energy
to move. Dancer
can rest up before
a dance starts so
they have more
energy to move
later.
Newton’s 1st Law of
Motion
An object at rest tends
to stay at rest and an
object in motion tends
to stay in motion with
the same speed and in
the same direction. A
moving body would
continue moving
forever in the absence
of an outside force.
Dancer tend to slow
down and stop by
themselves.
Newton’s 2nd Law of
Motion
 There are three
physical laws which
provide relationships
between the forces
acting on a body and
the motion of the
body.The greater
force behind a
dancer the faster he
or she will move. I
think the more force
the dancer have the
more they will move.
Newton’s 3rd Law of
Motion
 There are actions
that have the equal
and opposite
reaction.The amount
the dancer you jump
up the same amount
the dancer will come
back down.
Conclusion
 I think dance would not
exist without science. Our
body needs a lot of energy
to dance and move
around.The greater the
force, the more the dancer
will move.With out electric
energy the dancer would not
be able to listen to music
because they need
electricity to listen to music.
Dancer tend to slow down
and stop by themselves
which is Newton’s Laws of
Motion.
