Chapter 9 Notes: Energy
Energy: _________________________________________________________________________________
 Expressed in ___________ (J)
 When a given amount of __________________ is done, the same amount of ____________ is
involved.
Kinetic Energy: _________________________________________________________________________
 All _________________ objects have kinetic energy.
 Objects with kinetic energy can do ______________________.
 Depends on the __________________ and __________________. (Especially velocity.)
Potential Energy:
_____________________________________________________________________________________________
_____________________________________________________________________________________________
Mechanical Energy: __________________________________________________________________
_______________________________________________________________________________________
Potential Energy + Kinetic Energy = Mechanical Energy
Energy Conversion _______________________________________________ ________________________;
any form of energy can be converted into another form
Energy Conversion Examples:
 A radio is turned on  ____________ Energy to __________ Energy
 A shining flashlight  ____________ Energy to ____________ Energy to _________ + thermal
energy
*** When energy is used to overcome friction, some of the energy is converted to _____________
energy.
Law of Conservation of Energy: ______________________________________________________________
_____________________________________________________________________________________________
 Energy is not lost - it just gets converted into other forms.
Practice – State the energy conversion that is taking place in each situation.
1. Jenny wants to make waffles for breakfast. She plugs in the waffle iron to heat it up.
2. She mixes up the batter and then pours it onto the waffle iron. The mixture sizzles.
3. When the waffle is done cooking, it is a nice golden brown!
Energy Transformation Practice:
1. What energy transformations occur when you start a fire?
2. What energy transformations occur when you start your hair dryer?
3. What energy transformations occur when you toast a piece of bread?
4. What energy transformations occur when you turn on speakers to play music (assume the speakers
work using a battery)?
5. Plants convert____________ energy to _________________energy.
6. When a match is lit, _____________energy converts to ______________and _____________energy.
7. When you pedal a bicycle, you convert _________________energy to _______________energy.
