Transcript of Untitled Prezi
By Chintan. Sound energy: Sound energy is caused when an
object is smacked or smashed and it
vibrates that causes sound energy.For
example when someone beats a drum
its surface vibrates ,which creates the
bang noise. Heat energy is the energy which is caused
when molecules in an object starts to move
because of heat.The more the molecules
move fast the more heat energy is
produced. For example when water is
heated the molecules in it move which
causes heat energy. Nuclear energy is the energy that is a result
of a nuclear reaction.It is not commonly used
but, is a really high source of energy.The sun
is a source nuclear energy. Potential energy It is the energy that a stationary object
contains when it is in use it turns into another form of energy.Supose a baseball is stationary and resting on the ground it contains potential energy but, when it is thrown the ball's energy turns into kinetic energy. Mechanical energy Mechanical energy is the energy that is possessed by an object due to its motion
or due to its position.An example is when a bow is drawn it poses mechanical
energy and when the bow is released it is transferred to it and it turns
to potential energy Thank you for watching. Electrical energy Electrical energy is the energy that we use in our day to day life.It uses coal as an energy source.It is usually created in factories.A T.V.,radio, laptop ,computer and fans etc use electricity as their power source . Chemical energy Chemical energy is created when chemical bonds are formed.Chemical bonds are found in atoms and molecules.Some substances absorb heat energy and change it into chemical energy.A matchstick has a lot of chemical energy stored in it. When the match is struck, it burns and the chemical energy in it produces heat energy and light energy.
