group 1
the process of learning about the natural world through observation and experimentation
science
force between 2 ojects depending on mass and distance
gravity
created when things are pulled past each other
friction
an educated guess
hypothesis
mass x gravity
the amount of space a substance takes up
volume
average. sum of all data divided by number of data points
mean
independent variable
a lab tool to accurately measure volumes of liquids
graduated cylinder
the curve that water creates in a container. you should read the bottom of it when measuring volume
meniscus
kelvin
fourth state of matter
plasma
temp scale based on freezing and boiling point of water (metric)
celcius
changing from solid state directly to gas state
sublimation
measured quantities or observations
data
rate of movement with a direction (vector quatity)
velocity
rate of change of velocity
acceleration
object at rest stays at rest, object in motion stays in motion unless acted on by an outside force
Newton's first law/ inertia
longest side of a right triangle
hypotenuse
metric unit of distance
meter
negatively charged subatomic particle
electron
=number of protons, in order on periodic table
atomic number
gas or liquid
fluid
mass per volume
density
the horizontal rows of the periodic table that show number of electron shells
periods
