Transformations
A roller coaster going down hill is an example of what energy transformation?
GPE to Kinetic
This keeps heat and light out of a house, reducing the energy to cool a house.
Window tint
What does it mean to change from one kind of energy to another?
Energy transformation
What is another name for motion energy
Kinetic
Speakers playing music is an example of what energy transformation?
Electrical to sound
What does insulation do to help a home's electrical efficiency?
Prevents the heat or ac from running more
What does it mean to move energy from one object to another?
Energy transfer
Where does a roller coaster have the most GPE?
Chemical to kinetic
Does turning off lights not in use demonstrate energy conservation or the law of conservation of energy.
Energy conservation
Energy of position or condition
potential energy
Why is the second hill on a roller coaster not as high as the first hill?
Because the roller coaster loses energy to thermal and sound energy, if it was as tall or taller, it would not reach the top
A muscle warming up
Kinetic to thermal
What is an example of energy conservation?
Using energy efficient devices, etc.
Energy stored due to an object's mass and height
gravitational potential energy
Mass and height
A light turning on
Electrical to light
What does it means to be more energy efficiency
Doing the same job using less energy
The scientific law that states that energy can be transferred or transformed by cannot be destroyed
Law of conservation of energy
Chemical to kinetic
Kinetic to thermal
