100
If an object’s kinetic energy is increasing what is happening to it’s potential energy
What is decreasing?
100
A type of energy that is due to the movement of molecules inside an object.
What is thermal energy?
100
The benefit of an electromagnet over a permanent magnet.
What is being able to turn it on or off?
100
Light bouncing off of a surface.
What is reflection?
100
Sound travels through this type of matter the fastest.
What are solids?
200
A type of potential energy that is related to an object’s height.
What is gravitational?
200
The transfer of thermal energy when molecules collide together. (Objects MUST be touching for the heat to transfer)
What is conduction.
200
A large coil of wire that spins inside of a magnetic field.
What is a generator?
200
Materials that cannot be seen through.
What is opaque?
200
The loudness of a sound will _______________ if the amplitude of a sound wave decreases.
What is decrease?
300
A type of energy that is due to an object’s motion.
What is kinetic energy?
300
Heat is transfered from ___________ to ____________.
What is hot to cold?
300
This is how positive and negative charges interact with each other.
What is being attracted?
300
Light waves are this type of a wave. (Also known as transverse waves)
What are mechanical waves?
300
The number of times an object (sound wave) vibrates per second.
What is frequency or hertz?
400
A type of potential energy that is related an object’s ability to stretch.
What is elastic energy?
400
The transfer of thermal energy when molecules mix together due to currents in fluids. (Warm fluids rise, cooler fluids sink)
What are convection currents?
400
This type of electric energy flows through an object.
What is a current?
400
Light bending as it travels through an object (such as water).
What is refraction?
400
This is the way that sound waves travel through matter. (what type of waves?)
What are longitudinal or compression waves?
500
A type of potential energy that is related to an object’s molecular structure.
What is chemical energy?
500
The transfer of thermal energy by electromagnetic waves (aka. heat waves)
What is radiant energy?
500
A type of circuit that has more than one path for electrons to follow.
What is a parallel circuit?
500
The difference between visible light waves and those that are not visible.
