Energy and Power
By: Auguste Goodin
What is Energy
Energy is the ability to do work.
Kinetic Energy
Kinetic Energy is energy of motion.
• Example 1- A ball rolling down a hill.
• Example 2- Running
Potential Energy
• Potential Energy is energy that is stored in an
object.
• Example 1- A bike on top of a hill waiting to get
the energy out by going down the hill.
• Example 2- Sleeping before awakening to alarm
clock.
Chemical Energy
Chemical energy is the energy stored within
chemical compounds.
• Example 1- Batteries.
• Example 2- Burning a candle.
Mechanical Energy
Mechanical energy is the kind of energy that can
do mechanical work directly.
• Example 1- An airplane soaring through the sky
has mechanical energy.
• Example 2- A guitars strings being plucked.
Electrical Energy
Electrical Energy is really the effect moving
electrical charges from one point to another.
• Example 1- That charge of electricity moving
through the power lines.
• Example 2- A microwave.
Energy Conversion
One important property of energy is it’s ability to
change from one form to another form.
• Example 1- Chemical Energy from fossil fuels
(Coals, Oil, and Natural Gases) can be
converted into Heat Energy.
Law of Conservation of Energy
The fundamental principle of physics that the total
energy of an isolated system is constant, despite
internal changes.
• Example 1- When water is used to produce
electricity.
