Forms of Energy
This form of energy can be seen
Light Energy
A computer monitor changes this type of energy into light energy to display an image
This is a path through which electrical energy can flow.
Electrical Circuit
This tool makes nearby flowers and insects appear larger.
Hand lens
When light bounces off a mirror, this happens.
reflection
This form of energy moves through wires.
Electrical Energy
A flashlight transforms energy from its battery into this visible form of energy.
Light Energy
These three basic items are needed for a simple circuit that lights a bulb.
Battery, wires, and a light bulb
This curved, transparent part bends light to magnify an image.
lens
When light changes direction as it enters or exits glass, this happens.
refraction
Stored in chemical bond, this form of potential energy can be released when a fuel burns.
Chemical Energy
This type of energy is produced when a generator converts the kinetic energy of moving wind.
Electrical energy
To complete a circuit with a battery’s positive and negative terminals and an LED’s two leads, one wire connects the positive terminal to one LED lead, and the other wire connects the negative terminal to this remaining LED lead.
This instrument uses lenses to magnify tiny objects such as cells and bacteria.
microscope
This describes a material, such as apple juice, that lets some light pass through but not all of it.
translucent
This form of energy is related to the motion of particles in matter.
Thermal Energy
A coal-fired power plant uses this form of energy to make steam that spins a turbine.
Thermal energy
These two metal objects can replace wires in a simple circuit because they conduct electricity.
Two nails
This type of lens in a telescope bends light rays to help form a magnified image.
lens
When light enters the eye, the back of the eye does this to the light.
absorb the light
A battery stores this kind of energy, which a flashlight can transform into light.
Chemical Energy
A device changes electrical energy into this form when a hair dryer warms the air.
Thermal Energy
In a circuit with four separately connected LED branches and a shared return wire, cutting a connection between two branches leaves the other LEDs lit. Cutting the shared return wire makes the LED nearest that break go dark. This kind of circuit path allows other branches to keep working when one branch is interrupted.
Parallel circuit
This type of vision makes distant objects look blurry because the eye’s lens is too curved.
nearsightedness
The coating inside an optical fiber does this to light, keeping it traveling along the fiber instead of escaping through the sides.
