|
an “if ..then “ statement
|
|
INDEPENDENT VARIABLE
|
a factor that you can control or adjust
|
|
INIERTIA
|
the tendency of an object to resist being moved or if that object is already in motion, its tendency to resist a change in speed or direction until an outside force acts upon the object
|
|
KILOGRAM
|
the base SI unit of mass
