Energy Conversions

• Physical Science
• Chapter 9 Section 2

2
What is an energy conversion?

• Energy Conversion a change from one form of
  energy to another
• Any form of energy can change into any other form
  of energy

3
Kinetic Energy and Potential Energy

• Look at the animation above. What happens to the
  potential and kinetic energy levels?

4
Why do some people say that breakfast is the most
important meal of the day?

• Chemical energy of food is converted into kinetic
  energy when you are active.
• It is also converted into thermal energy to
  maintain body temperature.

5
Why are energy conversions important?

• Energy conversions are needed for everything we
  do.
• Heating our homes, getting energy from a meal
• Machines help harness the energy, and make the
  energy work for you.
• Electrical energy by itself wont dry your hair
  or light up a room

Energy Conversion Example
An alarm clock converts electrical energy to
sound energy, thermal energy, and light energy
Thermal Energy
Sound Energy
Electrical Energy
Light Energy

• Draw a flow map showing the flow of energy
  transformations in a car from starting vehicle to
  driving. You should have 5 different types of
  energy.

Can you think of More? Complete your graphic
organizer to illustrate energy conversions. Draw
a picture to represent 2different energy
conversions you may encounter in everyday life.
Be sure to explain what type of energy it starts
with and what type of energy it ends with.
