hello friends how's it going today so
what's up hey ever wondered what energy
is well it is the ability to do work
want to know more about energy come on
then zoom in energy can be found in a
number of forms when you eat the body
breaks down the food and gives you
energy to work and play when you go to
school you receive the sun's energy in
the form of heat and light and while
coming back from playing the street
lights use electrical energy to give you
light kinetic and potential energy are
the main forms of energy kinetic energy
is the energy that is in motion feel the
air around you that is kinetic energy
that's because it is moving
potential energy is the energy stored
inside an object if an object is not
moving and is still it means that it has
potential energy in it it is known to
have potential energy because if it is
released it would do a lot of work hey
watch this see this ball right now this
ball has potential energy in it this
means that this energy stored inside
this ball let's push this now see the
ball rolling well now it has kinetic
energy in it hmm so I'm going to tell
you something
that you must remember for the rest of
your lives energy can neither be
destroyed nor created but it can
transform from one form of energy to
another just how potential energy
transforms into kinetic energy
mechanical energy if an object has both
potential and kinetic energy at the same
time it is known as mechanical energy a
massive demolition ball is a good
example once the ball is at rest it has
potential energy once it starts moving
we know it has kinetic energy and when
it hits a wall we see some work being
done and that's because of the
mechanical energy chemical energy this
energy is caused by various chemical
reactions during the process of
digestion chemical energy is released
when food is broken down electrical
energy
when various electricity you know it is
the electrical energy see that lightbulb
giving out light and heat well that's
exactly what electrical energy is
gravitational energy it is the motion
caused by gravity simple example is when
an object is through the ground because
of the Earth's gravitational pull
trivia time plants use energy from
sunlight during photosynthesis only 10%
of energy in a lightbulb
is used to create light 90% of my
Bubbe's energy creates heat our
friendship is like energy and cannot be
destroyed so this is me
hangout
you
