,E = mc² - correct answer ✔✔mass-energy equivalence formulated by Albert
Einstein that demonstrates matter and energy are the same thing
electromagnetic energy
speed of light - correct answer ✔✔type of energy in x-rays, gamma rays, visible
light...:
speed of travel:
3 x 10⁸ m/s - correct answer ✔✔speed of light:
radiation - correct answer ✔✔energy emitted and transferred through space
true - correct answer ✔✔true or false:
radiation is ionizing and non-ionizing
ionization - correct answer ✔✔this occurs when an electromagnetic wave, or
subatomic particle, has enough energy to remove an orbital electron from an
atom
x-rays, gamma rays, ultraviolet light - correct answer ✔✔forms of electromagnetic
radiation with enough energy to ionize
alpha and beta particles - correct answer ✔✔particle type of radiation with
enough energy to ionize
,base quantities - correct answer ✔✔building blocs of all other quantities (mass,
length, time)
mass
kilograms (kg) - correct answer ✔✔quantity of matter contained in any physical
object:
unit of measurement:
true - correct answer ✔✔true or false:
mass remains unchanged regardless of state
derived quantities - correct answer ✔✔a combination of one or more base
quantities (volume, velocity, acceleration, force..)
Wt = mg, where m = mass, g = gravity
Newton (N) - correct answer ✔✔formula for weight:
SI unit:
weight - correct answer ✔✔the _____ of an object can change depending on
gravity, but the object's mass will always stay the same
energy - correct answer ✔✔ability to do work
Law of Conservation of Energy
, Law of Conservation of Matter - correct answer ✔✔laws that states that energy
and matter can change from one form to another, but cannot be created or
destroyed
potential energy
like a ball suspended above the ground - correct answer ✔✔ability to do work by
virtue of position:
example:
PE = mgh, where m = mass, g = gravity, h = distance above the earth

like a ball falling to the ground - correct answer ✔✔the energy of motion:
example:
KE = ½mv², where m = mass, v = velocity
Joule (J) - correct answer ✔✔formula for kinetic energy:
SI unit:
velocity (v)
v = d/t, where d = distance, t = time
