inertia
mass per unit volume.
density
a usually reversible change in the physical properties of a substance, as size or shape:

word that means not moving
static
pertaining to motion.
kinetic
one in which the subject or a group would not be tested for the dependent variable(s)
control
a proposition, or set of propositions, set forth as an explanation for the occurrence of some specified group of phenomena, either asserted merely as a provisional conjecture to guide investigation (working hypothesis ) or accepted as highly probable in the light of established facts.
hypothesis
a result, issue, or outcome;
conclusion
the quality or property of being soluble; relative capability of being dissolved.
solubility
the state of being malleable, or capable of being shaped, as by hammering or pressing:
malleability
the capacity to undergo a change of physical form without breaking; malleability or flexibility:
ductility
the quantity of motion in a moving body, the producer of its mass and velocity
momentum
movement under the force of gravity
free fall
a form of motion experienced by an object going around earth in a curved line
projectile motion
the tension of the surface of a liquid caused attraction of particles in the upper layer of said liquid
surface tension
the intensity of heat in/on an object; a measure of the average kinetic energy of the particles in an object
temperature
coldest possible temperature, where all molecular motion stops
absolute zero
a thickness of a liquid
viscosity
force/area ; continues physical excerpted on an object by smth in contact w/ it
pressure

Charles
solid to gas
sublimation
gas to solid
deposition
a reaction w/ absorption of heat
endothermic
a reaction w/ release of heat
exothermic

condensation
a substance w/ no define shape
liquid
SI unit for pressure
pascal
upward force exerted by any fluid upon a body placed on
buoyant force
shiny, clear; describes the periodic translational ordering of atoms or molecules within a solid.
crystaline
liquid to gas
evaporation
SI unit for work
joule
tall container w/ volume scale
cylinder
lipped cylinder glass container
beaker
measure of energy transfer that occurs when an object is moved over a distance by an external force at least part of which is applied in the direction of the displacement. ⬅⬅ ⬆⬆
work
time rate of doing work or delivering energy, expressible as the amount of work done W, or energy transferred, divided by the time interval t—or W/t
power
the SI unit of power, equivalent to one joule per second, corresponding to the power in an electric circuit in which the potential difference is one volt and the current one ampere.
watt
the ratio of the force produced by a machine to the force applied to it, used in assessing the performance of a machine.
mechanical advantage
measure of the effectiveness with which a mechanical system performs
mechanical efficiency
a simple machine made of a rigid beam and a fulcrum.
lever
the point on which a lever rests or is supported and on which it pivots.
fulcrum
a wheel with a grooved rim around which a cord passes. It acts to change the direction of a force applied to the cord and is chiefly used (typically in combination) to raise heavy weights.
pulley
a plane inclined at an angle to the horizontal. [ramp]
inclined plane
a mechanism that converts rotational motion to linear motion, and a torque (rotational force) to a linear force
screw
the SI base unit of electrical current.
amps
the SI unit of electrical resistance, expressing the resistance in a circuit transmitting a current of one ampere when subjected to a potential difference of one volt.
ohms
