ENERGY
TRANSFORMATION
WHAT IS ENERGY?
■ Energy is the ability to do work.
■ Energy is everywhere and it can do a lot of things.
Energy is invisible.
■ Energy can be classified into two types: kinetic and
potential energy.
FORMS OF ENERGY
POTENTIAL ENERGY
■ Is the energy possessed by a body by virtue of
its position or state.
■ Potential energy isn’t transferrable and it depends on the
height or distance and mass of the object.
■ Potential energy tends to affect the object within the
environment if and only when it gets transformed into other
kinds of energy.
KINETIC ENERGY
■ Every moving object and particle has kinetic
energy.
■ A person walking, a soaring baseball, a crumb
falling from a table and a charged particle in
an electric field are all examples of kinetic energy
at work.
■ Potential energy is converted to kinetic energy
when a force such as gravity acts upon the object
to set it in motion.
Energy can be transferred as
light.
■ Light energy is the only form of energy we can see.
■ Light energy is a form of electromagnetic radiation. Light
consists of photons, which are produced when an object's atoms
heat up. Light travels in waves and is the only form of energy
visible to the human eye.
■ Light from the sun helps plants grow and makes food for us to
enjoy. The sun’s energy also powers solar cells, which can be
used to create electricity.
■ The light energy moves through space until it encounters a solar
