Energy is the ability to do work or cause change.
The Law of Conservation of Energy states that energy cannot be
created or destroyed. It may be transformed from one form into another,
but the total amount of energy never changes.

Kinetic
energy
is the
energy an
object has
due to its
motion.
Heat energy
is the
transfer of
thermal
energy.
Chemical
energy
is energy
stored in
particles of
matter.
.
Kinetic energy increases as an object moves faster

When we eat our body uses chemical energy as fuel to help up grow
Chemical energy can also be stored in batteries ,matches fuel
Electrical
energy
is the energy
flowing in an
electric
circuit.
Electrical energy can be transformed into light or motion, and can
Mechanical
energy
is the
energy due
to the
motion and
position of
an object.
Every object in motion contains mechanical energy.
produce thermal energy/ Heat.
Machines such as steam engines can convert mechanical energy into other
forms of energy.
The electric motor makes mechanical energy from electrical energy while
a generator performs the opposite.
