Energy transformation
When energy changes from one form to another, this is called what?
energy transformation
Opposite charges will do this when they come near each other.
attract
Energy of motion
kinetic energy
A material that prevents electricity from flowing easily is called what?
insulator
Something that is clearly seen or understood.
evident
A roller coaster going down a hill changes potential energy into what type of energy?
Kinetic
In a simple circuit, electrons move through a wire from the battery to power a device like a light bulb. This steady flow of electric charge is known as what?
electric current
Energy that travels in waves you can hear.
sound energy
The rubber coating around wires helps protect you because it is this type of material.
insulator
A soccer ball rolling across the field has this type of energy.
kinetic
When a speaker changes electrical energy into vibrations you can hear, this type of energy is produced.
Sound energy
In this type of circuit, all components are connected in one continuous path, so if one part stops working, the entire circuit stops.
series circuit
A stretched rubber band has this type of energy.
potential energy
A material that allows electricity to flow easily through it is called what?
conductor
When light bounces off a surface.
reflection
When you rub your hands together and they get warm, what energy transformation is taking place?
mechanical energy to thermal (heat) energy
Two objects with the same type of charge will do this when placed close together.
repel
A roller coaster at the top of a hill has this type of energy
potential energy
Provide an example of a conductor
What type of energy transformations are there in a robot?
mechanical, sound, kinetic, electrical, light
A toaster converts electrical energy into what type of energy to toast bread?
Thermal Energy
In this type of circuit, electricity has more than one path to travel, so if one light bulb goes out, the others can still stay on.
parallel circuit
The ability to do work.
energy
Why is it dangerous to touch a metal object that is connected to electricity?
because metal is a conductor that allows electric current to flow through it
When light passes from air into water and bends, this phenomenon is called what?
refraction
