Gravitational, electromagnetic, weak, and strong forces
What are the 4 fundamental forces of the universe?
100
This force brings 2 masses together.
What is the gravitational force?
100
This type of waves requires no medium to transmit energy.
What is electromagnetic?
100
These are the three components of a circuit related in Ohm's Law.
What are voltage, current, and resistance?
100
This type of reaction releases large amounts of energy in the form of gamma photons when the nuclei of certain atoms split apart.
What is fission?
200
Which of the 4 forces of the universe is the strongest?
What is the "strong force" or "strong nuclear force"
200
This force is responsible for 2 like charges repelling.
What is the electromagnetic force?
200
Lenses depend on this property of light.
What is refraction?
200
This type of circuit has only one path for current.
What is a series circuit?
200
This type of reaction release large amounts of energy when two Helium atoms are fused together?
What is fusion?
300
Gravitational force
What is the weakest of the 4 fundamental forces of the universe?
300
This force is responsible for holding the nucleus of an atom together.
What is the strong force?
300
The angle of incidence for a ray of light striking a plane mirror will equal this according to the Law of Reflection.
What is the angle of reflection?
300
This type of circuit has more than one path for electric current.
What is a parallel circuit?
300
This process emits an electron when a photon of light strikes a metal with enough energy.
What is the photoelectric effect?
400
The strong force
Which of the 4 fundamental forces is responsible for holding the protons and neutrons together in the nucleus of an atom?
400
This force acts in the nucleus at short-range.
What is the strong force?
400
This determines how many photons are coming from a light source?
What is intensity, or brightness?
400
The purpose of this is to lower voltage from power lines into homes to safe, usable levels.
What is a "step down" transformer?
400
This pattern of colors measured from the emission of photons from an atoms different energy levels can identify the type of atom.
What is emission spectra?
500
This force is responsible for the radioactive decay of certian atomic nuclei
What is the weak nuclear force?
500
This is the order of the 4 forces, from strongest to weakest.
What is gravitational, weak force, electromagnetic, strong force?
500
In order to cause electrons to be emitted with more velocity using the photoelectric effect, photons must have more of this: energy or intensity.
What is energy?
500
This type of circuit always has the same current: series or parallel?
What is a series circuit?
500
This relationship states that energy and mass are equivalent when mass is traveling at the speed of light.
