Electric Eels
increases with increasing charge and decreases with increasing distance. It can either be attractive or repulsive
what is electric force?
mass/volume
what is density?
mantle, oceanic, continental
the earth's crust
internal energy is transferred because of differences in temperature
what is heat conduction?
distance/speed
what is time?
k
force per unit area of contact
what is pressure
mass is neither created nor destroyed.
what is the conservation of mass?
transfer of energy from one place to another as light ex. light passing through window pane
what is radiation?
a consequence of the special theory of relativity. a clock moving with respect to an observer will run slower than when it's at rest.
what is time dilation?
objects with the same charge repel each other and opposite charges attract
*cue Paula Abdul singing opposites attract
what is electrical force law?
weight before, weight after (net force of forces pushing up on the bottom and down on top)
What are buoyant forces?
the difference between the total amount of positive and negative charges does not change.
what is the conserrvation of electric charge
processes by which internal energy is moved from place to place as matter
what is convection?
the location in space and time where the observer makes a measurement.
what is reference frame?
contain a few free electrons, materials that do not permit the free motion of electrons and materials that do
what are semiconductors, insulators and conductors?
idea, experiments, predict, experiment, result, validate, theory
what is the nature of scientific laws?
the momentum of the rocket with the momentum of the exhaust
what is linear momentum?
atoms are bonded together or released from bonds to one another in such a way as to store or release chemical potential energy.
what is a chemical reaction?
a fundamental particle similar to the electron but much more massive
what is a muon?
complete interaction due to electric charge
what is electromagnetic charge?
an object immersed in fluid experiences an upward buoyant force due to contact interactions with a surrounding fluid whose strength is equal to the weight of the displaced fluid. Depends on the DENSITY of the submerged fluid
what is the Archimedes principle
these three do not have a conservation law associated with them
stored potential energy is transformed into internal thermal energy
what is combustion?
The idea that the laws of physics are the same and can be stated in their simplest form in all inertial frames of reference. Also, the idea that the speed of light c is a constant, independent of the relative motion of the source.
What are the 1st and 2nd postulates of the special theory of relativity
