It is a variable that stands alone and isn’t changed by the other variables you are trying to measure
Technology
the systematic study of the structure and behavior of the physical and natural world through observation and experiment
control

Mass
a quantitative measure of inertia, a fundamental property of all matter.
Scientific theory

Scientific law

experiment
a scientific test in which you perform a series of actions and carefully observe their effects in order to learn
Scientific Method
the technique used in the construction and testing of a scientific hypothesis.
SI
a scientific method of expressing the magnitudes or quantities of important natural phenomena.
graph
that represents the variation of a variable in comparison with that of one or more other variables.
