the study of the motion of objects
What is Kinematics
100
An American physicist he performed an oil drop experiment that demonstrated that all charges are a multiple of a fundamental unit of charge.
What is Robert Millikan? (1868–1953)
100
Fbeats=|f2-f1|
What is beat frequency equation?
100
in a wave or a sine curve that represents simple harmonic motion, the distance from equilibrium to the peak
What is Amplitude?
100
v= v0 + at
What is the 1st kinematics equation?
200
the highest point that a wave is displaced from equilibrium
What is Peak
200
The Danish physicist who discovered that electric currents create magnetic fields.
What is Daguerreotype of Hans Christian Oersted? (1777–1851)
200
this occurs when a incident light encounters another medium and bounces back into its original medium
What is Reflective Light Ray?
200
the lowest point a wave is displaced from equilibrium
What is Trough?
200
This was the first person to formulate ideas about how to describe the causes of motion
What is Sir Isaac Newton?
300
The relationship between potential difference, electric current, and reistance for a given circuit element
What is Ohm's law?
300
a French physicist, who was the first person to quantify the force between two or more electric charges.
What is Charles-Augustin de Coulomb? (1736–1806)
300
an initial light ray that is moving through one medium and then encounters another medium
What is Incident light ray?
300
quantities that need both a numerical value and a direction to fully discribe them
What is Vectors?
300
This person determined that the rate of acceleration due to gravity was about 9.80 m/s2
What is Galileo Galilei?
400
a resistive force that arises when two objects rub against each other
What is Friction?
400
EMF?
What is ElectroMotive Force?
400
If the two waves (each of amplitude A) overlap such that the peak of one wave is at the same position as the trough of the other wave at the same time, then their amplitudes superpose to make an amplitude of zero.
What is Destructive Interference?
400
The study of what causes the motion of an object to occur
What is Mechanics?

F=mg
What is force?
500
The mathematical relationship that measures how much force will be felt between two charged objects at a certain distance from one another
What is Coulomb's Law?
500
This Rule states that the sum of the voltage difference across all the elements around any closed circuit must be zero:
What is Kirchhoff’s loop rule?
500
As this light ray enters the new medium, it will bend and change direction.
What is Refraction?
500
in a wave, the distance between adjacent peaks or adjacent troughs
What is Wavelength
