There are seven base units in the system, from which other units are derived. Universal for comparing data.physical sciencethe sciences concerned with the study of inanimate natural objects, including physics, chemistry, astronomy, and related subjects.life sciencethe study of living things

controlled experimentAn experiment in which only one variable is manipulated at a time. Or a condition that is being held constant independent variablewhat is being changed dependent variablewhat is being measured controlIn an experiment, the standard that is used for comparison Observational experiment or studystudies attempt to understand cause-and-effect relationships. However, unlike experiments, the researcher is not able to control (1) how subjects are assigned to groups and/or (2) which treatments each group receives. ... Therefore, a sample survey is an example of an observational study.field studya research investigation carried out in a naturally occurring setting laboratory studyResearch done in a laboratory Physical ModelA physical representation of an object. Prototypes and appearance models are physical models.conceptual modela verbal or graphical explanation for how a system works or is organized mathematical modelone or more equations that represent the way a system or process works HypothesisA testable prediction, often implied by a theory TheoryA hypothesis that has been tested with a significant amount of data. Explains why something happened.LawA law in science is a generalized rule to explain a body of observations in the form of a verbal or mathematical statement. Scientific laws (also known as natural laws) imply a cause and effect between the observed elements and must always apply under the same conditions. Explains how it happened not why.ObservationInformation obtained through the senses.evidenceproof DataFacts and statistics collected together for reference or analysis Big Bang TheoryCosmological model that explains the sudden development of the universe through expansion from a hot, dense state.plate tectonicsA theory stating that the earth's surface is broken into plates that move.atomic theorya theory that states that all matter is composed of tiny particles called atoms.grama metric unit of mass equal to one thousandth of a kilogram.

meterThe meter is the basic unit of length in the SI system of units. ... The previous definition of the meter was one ten-millionth of the distance from the geographic north pole to the equator, measured over the earth's surface in a circle running through Paris, France.secondSI base unit for time CelsiusMetric unit for measuring temperature; On this scale water freezes at zero and boils at 100.KelvinThe SI base unit of temperature literBasic unit of volume in the metric system Metric PrefixesGiga, Mega, Kilo, deci, centi, milli, micro, nano derived unitA unit defined by a combination of base units direct relationshipa relationship in which one variable increases with an increase in another variable inverse relationshipa relationship in which one variable decreases when another variable increases SpeedThe distance an object travels per unit of time VelocitySpeed in a given direction Accelerationthe rate at which velocity changes over time; an object accelerates if its speed, direction, or both change distanceThe length of a path between two points DisplacementDistance and direction of an object's change in position from the starting point.Balance forceEqual forces acting on one object in opposite direction. These forces then give a

• net force, causing the object to stay in place.

unequal forceunbalanced forces cause a change in motion; speed. and/or direction. When two forces act in the same direction on an object, the net force is. equal to the sum of the two forces. When two unequal forces act in opposite directions.net forceThe combination of all forces acting on an object Newton's First LawAn object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.Massthe amount of matter in an object InertiaThe tendency of an object to resist a change in motion Newton's Second LawForce equals mass times acceleration Newton's Third LawFor every action there is an equal and opposite reaction FrictionA force that opposes motion between two surfaces that are in contact GravityGravity is the force by which a planet or other body draws objects toward its center. The force of gravity keeps all of the planets in orbit around the sun.gravitational forcean attractive force that acts between any two objects Momentumthe force or speed with which something moves law of conservation of momentumOne of the most powerful laws in physics is the law of momentum conservation. ...For a collision occurring between object 1 and object 2 in an isolated system, the total momentum of the two objects before the collision is equal to the total momentum of the two objects after the collision.workForce exerted on an object that causes it to move Energythe ability to do work
