The property of a material that tells us what the resistance would be of a cubic meter of that material-
Resistivity
A substance that does not readily allow the passage of heat, electricity, or sound-
Insulator
Describe the force of attraction or repulsion between two electric charges-
Colomb's Law
Object or type of material that allows the flow of an electrical current in one or more directions-
Conductor
A fundamental property of matter that is affected by an electric field. It is measured by an excess or deficient of electrons on an object-
Electric Charge
The force between objects caused by their electric charges-
Electrostatic Force
The resistance to motion of one object moving relative to another. It is the result of the electromagnetic attraction between charged particles in two touching surfaces.
Friction
By having two objects TOUCH each other and transfer electrons from one object to the next-
Conduction
By electrons to move from one object to the other without touching-
Induction
Circuit elements connected in a single path for the current to flow though-
Series Circuit
An electrical safety device that operates to provide overcurrent protection of an electrical circuit. ...Short circuits, overloading, mismatched loads, or device failure are the prime reasons
Short Fuse
Circuit elements are connected to where the current splits and then comes back together. Elements connected will have the same potential difference across them.
Parallel Circuit
The stationary point(s) on a standing wave where the amplitude is a minimum-
Node
The result of the restive motion between a wave source and an observer, where there is an apparent shift in the frequency of the waves. The effect does not change the actual frequency of the source, but rather the apparent frequency heard by the observer
Doppler Effect
Positions on a standing wave with the maximum amplitude-
Antinode
Imagine that the resistors in parallel (R2 and R3) were a single resistor. How would the combined equivalent resistance of R2-R3 compare to the resistance of R1.
R2-R-3 is half of R1
At which point will the roller coaster have the greatest amount of potential energy?
A (The highest point)
Energy produced from the fusion or fission of molecular atoms.
Nuclear Energy
Potential energy is sometimes called _____ energy.
Stored
This energy holds the protons together in the nucleus.
Nuclear Energy
Which of the following is the only one that affects the period of a pendulum?
String Length
A disturbance or oscillation that travels through space-time, accompanied by a transfer of energy.
Resonance
A substance that makes possible the transfer of energy from one location to another, especially through sound waves.
Medium
The wave may propagate in any direction, but the disturbance of the medium is perpendicular to the direction of propagation.
Transverse Wave
