Transformations
Rube Goldberg machines are designed and constructed to demonstrate this:
What are energy transformations?
This term is best defined as "to show"?
What is indicate?
A modified radiometer is constructed with the four inner flags painted solid black on both sides of each flag. A stypical radiometer has one side of each flag painted white, and one side painted black. When exposed to a strong light source, the flags on the the modified radiometer are expected to:
What is remain stationary?
Energy due to motion is called:
What is kinetic energy?
The thin wire in a flashlight bulb that produces light is called:
What is the filament?
These human sense(s) are used to detect an energy transformation:
What are tasting, touching, smelling, hearing, and sight?
A student writes a plausible conclusion that was based on observations the student made. This term best describes the process completed by the student:
What is an inference?
This energy transformation occurs when a typical radiometer is exposed to a strong light source:
What is light to heat to mechanical energy?
Which types of material can light travel through?
What are water, empty space, and air?
A battery has:
True or False
A book at rest on a shelf is an example of an energy transformation.
What is false?
A spring is stretched and held motionless. The energy that the stretched spring has is best described as:
What is elastic potential energy?
A radiometer's relationship to light is similar to a pinwheel's relationship to:
What is wind?
This is not a form of energy:
What is pressure?
Most of the natural resources used to generate electricity in the United States are classified as being:
What are limited, nonrenewable?
Smoke emerges from a fire. This is an example of a(n) ____________________ of energy transformation.
What is an indicator?
Coal, oil and natural gas are forms of:
What are fossil fuels?
As the distance a light source is positioned from a radiometer increases, the spin rate of the flags in the radiometer:
What is decreases?
When a piece of wood is burned, heat is given off. The heat is produced when bonds between atoms and/or molecules are broken. The bond breaking is an example of this type of energy:
What is chemical energy?
Coal is best classified as being this type of natural resource:
What is limited, nonrenewable?
This illustrates the energy transformation when a battery-powered flashlight produces light:
What is chemical to electric to heat to light?
Plant and animal remains are the original source for:
What are fossil fuels?
This is the meaning of the root word "radio":
What is ray?
The energy of a moving electric charge:
What is electric energy?
Solar energy is best classified as being this type of natural resource:
What is unlimited, renewable?
