Answers Already Graded A+
Atomic Weight - CORRECT ANSWER-The weighted average of the masses of
the naturally occurring isotopes of an element, in amu per atom
Mass Number - CORRECT ANSWER-Superscript
Total number of protons and neutrons in a nucleus
Atomic Number - CORRECT ANSWER-Subscript
The number of protons in the nucleus of an atom, which determines the chemical
properties of an element and its place in the periodic table
Mole - CORRECT ANSWER-A unit used to count particles and is represented by
Avagadro's number
Mole=mass of a sample/molar mass
,Isotopes - CORRECT ANSWER-For a given element, multiple species of atoms
with the same number of protons but different numbers of neutrons
Average velocity - CORRECT ANSWER-v=Δx/Δt
unit: m/s
Acceleration - CORRECT ANSWER-a=Δv/Δt
unit: m/s^2
Linear motion - CORRECT ANSWER-vf=vi+at
Δx=vit+1/2at^2
vf^2=vi^2+2aΔx
Projectile Motion - CORRECT ANSWER-Vertical component of velocity vsinθ
Horizontal component of velocity vcosθ
Static friction - CORRECT ANSWER-The force that must be overcome to set an
object into motion
Fs ≤ μs η
,Kinetic Friction - CORRECT ANSWER-Opposes the motion of objects moving
relative to each other
Ff = μFN
Work - CORRECT ANSWER-W=F*d*cosθ
F is the force applied, d is the distance over which the force is applied, and θ is the
angle between the force applied and the direction of the object's movement
unit: joule=N*m
Power - CORRECT ANSWER-Rate at which work is performed
P=W/Δt
P=ΔE/t
Function of work over time
unit: watt= J*s
Kinetic Energy - CORRECT ANSWER-The energy associated with moving objects
K=1/2mv^2
Potential Energy - CORRECT ANSWER-Energy associated with a body's position
usually represented as U
, Gravitational Potential Energy - CORRECT ANSWER-U=mgh
Work Energy Theorem - CORRECT ANSWER-W=ΔE
Conservation of Energy - CORRECT ANSWER-ΔE=ΔK+ΔU=0
Newton's First Law - CORRECT ANSWER-A body in a state of motion or at rest
will remain in that state unless acted upon by a net force
Newton's Second Law - CORRECT ANSWER-F=ma
unit: newton= kg*m/s^2
Newton's Third Law - CORRECT ANSWER-Fb=-Fa
If body a exerts a force on bode b, then body b will exert a force back on a that is
equal in magnitude but opposite in direction
Newton's Law of Gravitation - CORRECT ANSWER-F=Gm1m2/r^2
Force, uniform circular motion - CORRECT ANSWER-Fc=mv^2/r
