Energy is the capacity of a physical system to perform work. Energy exists in several forms such as heat and electricity. According to the law of conservation of energy, the total energy of a system remains constant, though energy may transform into another form.
You are reading
this and your eyeballs are letting you see things by collecting energy from the
world around you. That energy is light! Everything we see gives off light. The
Sun, the Moon, a lamp. Light bounces off other things - A mirror, a tree, a
person.
Two billiard balls
colliding may come to rest with the resulting energy becoming sound and a bit
of heat at the point of collision.
The SI
(International System of Units) unit of energy is the joule.
Energy is in us, and
all around us. It makes the planets swirl and the energy of our teeniest
subatomic particles give us life.
Just One Joule – Sharing with you a special Qi gong technique, sharing with you a special thought ... with the hope that it will be a small treasure in your day.
