Types of Energy
This type of energy is in an object that is moving.
Kinetic energy
How does sound energy travel?
In waves
What is a collision?
When an object bumps into another object
What is the ability to do work or cause change?
Energy
Is a wire an example of an insulator or a conductor?
Conductor
This type of energy is in an object that is not moving
Potential energy
Does a Kindergartener have a low or high-pitch voice compared to an 8th grader?
High-pitch
What is the definition of the transfer of energy?
When energy moves from one object to another.
When energy is changed from one type of energy into another, what is that called?
The energy is transformed
An electric current
This type of energy travels in waves through the air.
Sound energy
When looking at a wave of a high-pitch sound, does it looked squished together?
Yes
What is an electric current?
The flow of charged particles in the same direction.
This is a property that causes matter to have a force, called electric force.
Electric charge
If two particles have the same charge (positive and positive or negative and negative), will the particles push each other away or pull each other closer?
This type of energy transfers from something hot to something cool.
Thermal energy
Does a low-pitch sound have a long or short wavelength?
Long
What is the transfer of thermal energy from one object to another called?
Heat
A material that allows electric current to flow through it.
Conductor
What is a source?
The starting point of an electric current
Give an example of potential energy transferring into kinetic energy
A pen that was in someone's hand gets thrown across the room
When something has a low-pitch how does it vibrate (imagine a guitar string)?
Slowly
What is an insulator?
A material that does not allow electric current to flow through it.
A source
If two particles have opposite charges (one is positive and one is negative) what will the particles do to each other?
