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 won’t dry your hair or light up a room

6. 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

7. 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.

8. Energy Transfer Sound (mechanical) Electrical Thermal Mechanical

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.
