Gravitational force exerted on an object by Earth.
What is weight?
100
The transfer of energy that occurs when a force makes an object move over a distance.
What is work?
100
A material, such as copper wire, through which an excess of electrons can move easily.
What is a conductor?
100
The highest part of a wave.
What is the crest?
200
The distance an object travels in a certain amount of time.
What is speed?
200
Stored energy due to position.
What is potential energy?
200
The amount of work done, or the amount of energy transferred, in a certain amount of time.
What is power?
200
A material that doesn't allow electrons to move through it easily,
What is an insulator?
200
The lowest part of a wave.
What is the trough?
300
The speed and direction of a moving object.
What is velocity?
300
Energy in the form of motion.
What is kinetic energy?
300
A device that makes doing work easier by increasing the force applied to an object, by changing the direction of an applied force, or by increasing the distance over which a force can be applied.
What is a machine?
300
A circuit in which electric current has only one path to follow.
What is a series circuit?
300
The distance between two consecutive crests of a wave.
What is wavelength?
400
A force that opposes motion between two touching surfaces.
What is friction?
400
States that energy can never be created or destroyed.
What is the Law of Conservation of Energy?
400
A particle of light.
What is a photon?
400
A circuit in which electric current has more than one path to follow.
What is a parallel circuit?
400
The measure of how many wavelengths pass a fixed point each second.
What is frequency?
500
Resistance of an object to change in its motion?
What is inertia?
500
The ability to cause change.
What is energy?
500
Waves created by vibrating electric charges; can travel through a vacuum (like space), or through matter, and can have a wide variety of frequencies & wavelengths.
What is an electromagnetic wave?
500
Electricity generated when more of one type of charge is on an object.
What is static electricity?
500
The bending of a wave as it changes speed, moving from one medium to another.
