Quantitative Made by gathering information that can be recorded as a number with a measurement unit.
Inference Not a fact, but an interpretation of what the direct observations mean.
Scientific Law Describes what scientists expect to happen every time under a particular set of conditions.
Constant Part of an experiment that is held in the same condition for control and experimentation.
Variable Part of an experiment that changes.
Manipulative variable A factor in a controlled experiment that is intentionally changed by the experimenter
# 8
Question To ask for information.
Responding Variable A resulting factor in a controlled experiment that is observed and measured to see if it changes due to the manipulation of another variable.
Experiment A course of action completed in order to test a hypothesis.
Control A standard to which all other levels are compared in a scientific experiment.
Physical Properties Characteristics of a pure substance that can be observed without changing into another substance.
Chemical Properties A pure substance that cannot be broken down into other substances by chemical or physical.

Gravity
Newton's Law 1 An object at rest stays at rest or an object that is moving at a velocity in a straight line keeps moving at that velocity unless another object acts on it.
Newton's Law 2 The amount of force needed to make an object change it's speed depends on the mass of the object and the acceleration required.
Newton's Law 3 For every action there is an equal and opposite action.
Mechanical Advantage The ratio of the output force produced by a machine to the applied input force.
