Kinetic/Potential Energy
This is the energy of motion.
What is kinetic energy?
Energy changing from one form into another form is called:
Energy Transformation
Heat always travels from ___ objects to ___ objects.
hot; cold
This is Kinetic Energy + Potential Energy
What is Mechanical Energy?
Energy from an electric fan changes from electrical to ______.
What is mechanical energy?
This process allows light from the sun to be used to make food for plants.
What is photosynthesis?
This type of radiation is used to heat up your food and to make popcorn.
Microwave
This tells you how easy or difficult it is to heat something up.
Specific Heat
Two things that determine an object's kinetic energy:
mass and speed
The energy of an atom's nucleus.
What is nuclear energy?
This energy transformation takes place in a lightbulb
electrical energy to light energy
Heat transfer of direct contact
If an object heats up quickly, what can you know about its specific heat?
It is a low number.
What is elastic potential energy?
A battery has what type of energy?
What is chemical energy?

Light energy into mechanical energy
Hurricanes and tornadoes are examples of:
Convection
Why does water take a long time to heat up?
Because it has a high specific heat.
As a roller coaster car goes down a hill, ____ energy changes into _____ energy.
potential; kinetic
