physics chapter. 1

hypothesis

explaining why

law

observation made

Theory

an attempt to explain;constantly rewritten

physical model

can touch it

conceptual model

ideas expressed with words

math models

formulas relating to things

computer

rules and algorithms used to test theory

Thomas Kuhn

wrote the structure of scientific revolution

Force

measured in newtons

formula: mass(kg) x acceleration (m/s²)— ON EARTH (9.8m/s²)

Chem base units

meter, gram, second- gram bc all equations use gram

physics base units

meter, kg, second - kg bc all equations use it

measurements

all are approximations

only use sig figs with them

independent variable

x axis

dependent variable

y axis

curves

linear, quadratic, inverse

interpolation

predicting values within the bounds of he dataex

extrapolations

predicting outside of bounds of provided data

never use it
