What are 2 examples of the energy form?
Energy exists in many different forms. Examples of these are:
light energy, heat energy, mechanical energy, gravitational energy, electrical energy, sound energy, chemical energy, nuclear or atomic energy
and so on. Each form can be converted or changed into the other forms.
What are the 2 most common forms of energy?
After hundreds of years of observation and experimentation, science has classified energy into two main forms:
kinetic energy and potential energy
. In addition, potential energy takes several forms of its own. Kinetic energy is defined as the energy of a moving object.

What type of energy is food?
We get
chemical energy
from foods, which we use to run about, and move and talk (kinetic and sound energy).
What is the main source of energy?
One of the most important sources of energy is
the sun
. The energy of the sun is the original source of most of the energy found on earth. We get solar heat energy from the sun, and sunlight can also be used to produce electricity from solar (photovoltaic) cells.
