Newton's 1st Law - correct answersAn object at rest will stay at rest unless acted upon by an
unbalanced force
Newton's 2nd Law - correct answersForce = Mass * Acceleration
Newton's 3rd LAw - correct answersAll forces result from interactions between pairs of objects,
each exerting and equal and opposite force on the other
Existence - correct answersthe fact or state of having actual or real being
Causality - correct answerscause must always precede the effect
Position Symmetry - correct answersthe laws of the universe are the same everywhere
Principle of Non-contradiction - correct answersof two contradictory propositions, both cannot
be true
Time Symmetry - correct answersthe laws of the universe do not change with time
,Occam's razor - correct answersthe simplest explanation is most likely the right
Strong Nuclear Force - correct answersStrongest, shortest range, holds the nucleus of an atom
together
Electromagnetic Force - correct answers2nd strongest, it is the interactions between charged
particles
Acceleration - correct answersAny change in speed or direction
If there is acceleration - correct answersthere must be a force involved
Uniform motion - correct answersobject is at rest or is moving at a constant speed in a straight
line. All forces are balanced. (Elevator)
Weak Nuclear forces - correct answers3rd strongest, do not need to know anything else
Gravity - correct answersWeakest force, longest range. interactions between anything with
mass.
Newton's 3rd Law Collisions- A fly and the semi truck experience the ____ amount of forces -
correct answersSame
Newton's 3rd Law Collisions- A fly and the semi truck experience _____ accelerations - correct
answersdifferent, fly has a large acceleration while truck has a lower acceleration
All objects experience the same acceleration due to - correct answersgravity, but only in the
absence of air friction
, The force of gravity depends on - correct answersthe mass of the 2 objects and how far apart
they are
Heavier objects experience a - correct answersgreater gravitational force, but the same
acceleration
Force is - correct answersproportional to mass
Universal Law of Gravity - correct answersForce=GmM/d^2
Atoms are made up of - correct answersprotons, neutrons, and electrons
In a transfer of charge only - correct answerselectrons move
Electromagnetic force deals with - correct answersanything outside of the nucleus
The force between two charges depends on - correct answersthe size of the charge and the
distance between them
Electrical potential energy - correct answersenergy associated with the relative position of
charged objects
Like charges have the most potential energy when - correct answersthey are close together.
High potential to separate
Opposite charges have the most potential energy when - correct answersthey are far apart.
There is the potential to come together
