(1) Classical Physics & (2) Modern Physics2 main branches of Physics
Classical PhysicsTraditional topics in Physics
Classical Physicsdeveloped before the beginning of the 20th century
Mechanicsforces acting on body
AcousticsProduction and propagation of sound waves
OpticsLight
Thermodynamicsrelationship between & other energy forms
ElectromagnetismElectric current & magnetism and their relationship
Modern PhysicsConcepts in physics that have surfaced since the beginning of the 20th century
Nuclear/atomic physicscomponents, structure and behavior of nucleus of an atom
Quantum physicsFocus in the indivisible units of energy called quantum as described by the Quantum theory
Relativistic theoryPhenomena that take place in a frame of reference that's in motion w/ respect to an observer
Solid state physicsall property of solid material
Condensed matter physicsproperty of condensed materials with ultimate goal of developing new materials with better properties
Plasma physics4th state of matter
Low temperature physicsproduction & maintenance of temperature down to almost absolute zero & the various phenomena that occur only at such temp
Accuracyhow close a measurement to true value or accepted value
PrecisionDegree pf exactness to which a measurement can be reproduced
Scientific notationcompact way of writing over a wide range of values
Scientific notationnumbers represented by product of multiplying factor & power of ten
Measurementquantitative description of a fundamental property or physical phenomenon
Metric System of MeasurementDesignations of multiples and subdivisions of any unit may be arrived at by combining w/ name of the unit
Systematic Errors (Determinate)Due to limitations of measuring instruments and skill or carefulness of the experiment
Random Errors (Indeterminate)Cause by external factors beyond control of experimenter

Question Answer
Line of Best FitEyeball method
Direct ProportionAs one quantity increases, the other increases
Straight LineDirect Proportion shape
Inverse ProportionAs one quantity increases, the other decreases
Oblique HyperbolaInverse Proportion shape
Direct Square ProportionAs one quantity increases, the other increases faster
ParabolaShape of Direct Square Proportion
Inverse Square ProportionAs one quantity increases, the other decreases faster
Oblique HyperbolaInverse Square Proportion shape
VectorMagnitude & Direction
ScalarMagnitude only
Simple arithmeticAdding scalar
Simple arithmeticUsed for adding vector if they are in the same direction
Composition VectorProcess of adding the vector
Composition VectorAlso called as Vector Addition
Resultant Vectorrepresentation of sum
Tail-head methodSecond vector is drawn such that its connected to the arrowhead of the first vector
Parallelogram MethodTwo vectors, common origin
Polygon MethodFor more than 2 vectors

#3

Question Answer
(1) Inertia, (2) Acceleration, (3) InteractionNewton's Laws of Motion
Mass is scalar while Weight is vectorDifference between mass & weight
Role of doing work; joules per secondPower and it's unit of measurement
Law of InertiaLaw that stated that the total momentum of a system does not change if there are no net external forces acting on it
InelasticIt is when two objects collide and move together as one mass after collision, the collision is called ________________\
ElasticIt is the kind of collision, after two objects collide, they move separately with no chage in kinetic energy
ImpulseIt is the product of the net force acting on an object and tge time interval which in the force is acting
