What is Energy? |
-
Energy is in everything around us. It is in the air
you breath, the water you drink and the food you eat.
It is in the trees that grow as well as the wood we
use after the tree is dead.
-
Energy is the power to change things. It can make things
hot or cold, it can make things move or stop, it can
grow things and shrink things.
-
Energy is the ability to do work and can produce: Warmth,
Light, Sound, Movement, Growth or Powers Technology.
-
Energy cannot be destroyed or created. It can only
be transformed. This is Law of Conservation it is also
called the First Law of Thermodynamics.
-
Some energy is always lost in a transfer. No energy
transfer is 100% efficient.
Think about it!
Below are examples of energy. Look at each picture
and think about how each one has energy. How it can change
into a different form of energy and how it can do work? |
