What is motion?
Motion is the change in an objects's position.
100
What is energy?
Energy is the ability to do work.

When heat travels, does it go from hot to cold or cold to hot?
When heat travels it goes from hot to cold.
100
What is static electricity?
Static electricity is when there is an electric force between non-moving electrical changes.
200
What was Newton's first law?
Newton's first law is an object in motion will stay in motion unless a force stops it.
200
What are 3 types of energy?
Examples of three types of energy are: 1. Kinetic energy, 2. Potential energy, and 3. Mechanical energy.
200
What are conductors?
Conductors are materials that tranfer thermal energy.
200
What is what is an electric generator?
An electric generator is a device that converts mechanical energy into electricity.
300
What simple machine has a fulcrum?
A simple machine with a fulcrum is a lever.
300
What is the distance between two waves?
the distance between two waves is called wavelength.
300
What is conduction?
Conduction is when there is a transfer of thermal energy through direct contact.
300
What is are the disadvantages of a series circuit?
In a series circuit, if one bulbs goes out, they all go out. Another possible answer: In a series circuit, all of the lights are dimmer.
400
What is work?
Work is when a force moves an object over a distance.
400
What is refraction?
Refraction occurs when the path of light wave changes as it moves through materials to another.
400
What is convection.
Convection is the process for transfer of thremal energy through liquids and gases.
400
What are the advantages of parallel circuits?
Some advantages of parallel circuits are: 1. When one bulb goes out, the stay lit. 2. Lights are brighter.
500
What is an electromagnet powered by?
An electromagnet is powered by an electric current.
500
How do fiber optics work?
Fiber optics work when light bounces off the tubes then goes out.
500
What is radiation?
Radiation is the transfer of energy by electromagnetic waves.
500
What kind of transformer does electricity go thorough before it goes to you home?
Electricity goes through a transformer drum before it goes to your home.
