Forces & Fields
This is a short definition of force.
What is a push or pull?
This is the theory that all objects with mass exert gravitational force.
What is the law of universal gravitation?
These are the objects affected by electric and magnetic fields, respectively.
Electric: charges. Magnetic: magnets and currents.
This subatomic particle determines the identity of an element.
What is a proton?
"Nature is a language -- can't you read?"
These are the four fundamental forces.
What are gravity, electromagnetism, the strong nuclear force, and the weak nuclear force?
Isaac Newton knew THAT this happened but not HOW this happened.
Newton knew that objects affected each other at a distance via gravity but not how.
This is why there can be multiple positively charged particles fused together in the nucleus of an atom.
What is the strong nuclear force?
This force helps account for the fusion of hydrogen protons but not the conversion of nucleoids.
What is the strong nuclear force?
These are the Greek and Latin words from which we derive "physical sciences" along with the root words' meanings.
Phusis ("nature") + scire ("to know"): To know the nature of things.
These are the three geometric aspects of field.
What are strength, range, and direction?
This is the name and a description of the idea that Einstein used to explain gravitational forces affecting objects at a distance.
What is the general theory of relativity? What is the idea that the universe consists of spacetime fabric that is warped by massed objects?
Describe the shape of the field resulting from a positive charge and negative charge being beside each other.
The otherwise circular fields are bent: the field lines emerge from the positive charge and bend towards and into the negative charge.
This particle affects an elements mass but is not directly related to the number of electrons the atom has.
What is the neutron?
This is Mr. Cowart's dog's name and the president he's named after.
Theo. Theodore Roosevelt.
These are the four characteristics of each field that we learned.
What are strength, cause, affects, and shape?
This is what launched Albert Einstein to fame.
Albert Einstein correctly predicted that the light of stars would bend when they traveled passed the Sun during an eclipse.
The electric fields of electrons are negative, which repel other atoms' electrons, and most of the remaining atom is empty space.
This is the phenomenon of an atom losing subatomic particles, as well as the process by which neutrons convert into protons.
What are radioactive decay and beta decay?
Hello Mr. "Perfectly fine"
How's your heart after breaking mine?
Mr. "Always at the right place at the right time, " baby
Hello Mr. "Casually cruel"
Mr. "Everything revolves around you"
I've been Miss "Misery" since your goodbye
And you're Mr. "Perfectly fine"
This is the direction negative field lines point.
This is the law and graph representing the strength of a gravitational field.
What is an inverse-square law? And which graph is a negative U-shape?
This is how you can generate the effects of a block-shaped magnet without having a magnet on hand.
What happens when you coil current-carrying wire?
This the energy trail for a nuclear bomb.
The nuclear potential energy stored in fused nucleoids is released by fission, which becomes kinetic energy in thermal energy, sound waves, and electromagnetism.
Who is Mrs. Celano's daughter named after?
Saint Lucia
