forms of energy

types of energy
ability to do motion and heat kinetic potential
work (energy at work) (stored
energy (inactive)

Bodily Energy

Oxygen

contain energy the potential form


kinetic form through uniting
with each other in the body


Oxidation at the cells

Gravity

Through Elasticity

Storage depends on 3 principles:
The work done
The work must be against some force,
such as gravity and elasticity  undo the work
The stored energy becomes active (kinetic)

eats the food and breathes the oxygen, the potential

energy of the plants from the sun becomes the possession of the body;
Then it is converted into kinetic energy as the needs of the body require.
From the Sun to the cells:
‘the child of the Sun”– dependence upon the sun for our supply of energy.

and oxygen
can produce energy)

Rule: quantity of kinetic energy

supplied to the body is proportional to the work that is done.
It is done through the ability of the body to store up the food materials and hold them in reserve until they are oxidized.

is used to keeping warm;
Important for carrying on the

vital processes;
All parts of body (through oxidation) furnish heat (muscles, brain, liver – larger share);
Blood serves as a heat distributor.

the body;
Heat- producing exercise (in the open air);
Introduction of

the proper amounts of food and oxygen  efficiency of the vital processes.

and ventilated overheating rooms;
Wearing heavy clothing and sleeping under

excess of bed clothes;
Overworking your body – too much arousal;
Taking stimulants: alcohol, tobacco, strong tea and coffee  tend to exhaust the bodily resources.
