density (formula)
mass ÷ volume
speed (formula)
distance ÷ time
force (formula)
mass x acceleration
area of a triangle (formula)
1/2 x base x height
SLAP
scale, line , axis, point/plot
solids
contain shape + volume all the time
liquids
flowing particles that change shape and keep the same volume
gases
never keeps the same shape + volume
diffusion
movement of air particles from high low concentration
independent v
variable that is changed
dependent v
affected by THE change
controlled varible
varibales that keep the same
fair test
only one variable is changed
solute
dissolved in the solvent, minor component
solvent
solute dissolves in, the liquid

chromatography
pure substance
consists of only 1 element or compound
eg. water, air
insoluble
can’t dissolve
soluble
can dissolve
mass
amount of stuff in an object
weight
downward force of any object that FEELS DUE to it’s GFS
friction
a force created when 2 surfaces try to move or mover across each other
air resistance
a force that acts against objects that are moving through the air
speed (formula)
distance x time
time (formula)
distance ÷ speed
distance (formula)
speed x time
