Electricity
100
The energy of motion.
What is KINETIC ENERGY?
100
The cause of sound?
What is a vibration?
100
Materials that no light can travel through.
What is OPAQUE?
100
They make up all the matter around you.
What is an ATOM?
100
A circular path that electricity flows through.
What is a CIRCUIT?
200
The energy of position.
What is POTENTIAL ENERGY?
200
How high or how soft a sound is.
What is PITCH?
200
Material that almost all light can travel through.
What is TRANSPARENT?
200
The result when positive and negative charges do not balance.
What is static electricity?
200
The condition that is required in order for electricity to flow through the circuit.
What is the circuit must be closed?
300
What is MECHANICAL ENERGY?
What is the sum of potential and kinetic energy in an object?
300
What determines if a sound is louder than others?
What is the more energy the sound waves have, the more volume the sound will have.
300
Material that only some light can travel through.
What is TRANSLUCENT?
300
When charges attract, what is their relationship?
What is they are opposites (one positive and one negative)?
300
What is a conductor? Give an example.
A conductor is a material that allows electricity to flow through easily. An example would be copper wire.
400
What are some things that determine the amount of energy an object has?
The more mass an object has the more energy it will have. The faster an object, the more kinetic energy it will have. The higher the object is, the more potential energy it will have.
400
The differences between the frequency of waves in a HIGH PITCH and LOW PITCH sound.
What is a high picth has a higher frequency of waves and a low pitch has a less frequency of waves.
400
The difference between refraction and reflection.
What is reflection is the process in which light hits an object and bounces back. Refraction is the process in which light bends when hitting an object at a different angle than 90 degrees.
400
When you feel static electricity, what is occuring?
What is an electric charge is being passed from an object to you?
400
What is an insulator? Give an example.
What is a material that almost STOPS electric currents. An example would be an insulated chord made of rubber.
500
What are some of the types of potential energy?
What is gravitational potential which depends upon the position of the object relative to earth and elastic potential energy which is present when things are bent or stretched.
500
What is the process from sound being created to sound getting to your ear?
What is sound is started with a vibration which causes a sound wave that travels in any direction. It reaches your ear causing it to vibrate and a sound being heard.
500
What determines the colors you see in objects?
Whatever color an object reflects is the color you see. If an object reflects all colors it is white and if it absorbs all colors, it is black.
500
When an object is neutral what is that describing?
What is there is an equal number of positive and negative charges in the object?
500
Describe the position of a switch in order for a circuit to work and not work.
What is when a switch is closed, it allows electricity to flow through and powers the object. When a switch is open, it creates a break in the circuit not allowing the electricity to flow.
