  1. 5. a relation between two variables expressible by an equation of the form y=k/x
  2. 8. the SI unit for length, abbreviated (m)
  3. 10. relation between variables in which a constant change in the independent variable is accompanied by change in the dependent variable that is proportional to the value it already had
  4. 12. a quantitative measure of how much measured values deviate from a standard or expected value
  5. 14. inches, foot, miles, pound.
  6. 15. a quantity that does not change
  7. 17. way of writing numbers that are too large or small to be conveniently written in simple decimal form; the measurement is multiplied by a power of 10, which indicates the number of placeholder zeros in the measurement
  8. 19. any relation between variables where one variable decreases as the other variable increases

  1. 1. the SI unit for electrical current
  2. 2. the seven fundamental physical units in the SI system of units are length, mass, time, electric current, temperature, amount of a substance, and luminous intensity
  3. 3. the size of a quantity in terms of its power of 10 when expressed in scientific notation
  4. 4. the vertical, or y-axis, variable, which changes with (or is dependent on) the value of the independent variable
  5. 5. the horizontal, or x-axis, variable, which is not influence by the second variable on the graph, the dependent variable
  6. 6. a ratio expressing how many of one unit are equal to another unit
  7. 7. relation between variables that can be expressed in the form y=ax^2+bx+c , which produces a curved line when graphed
  8. 9. units that are derived by combining the fundamental physical units ]
  9. 11. relation between variables that produce a straight line when graphed
  10. 13. when writing a number, the digits, or number of digits, that express the precision of a measuring tool used to measure the number
  11. 16. meter, kelvin, kilogram, ampere
  12. 18. how well repeated measurements generate the same or closely similar results
  13. 20. the ratio of the change of a graph on the y axis to the change along the x-axis, the value of m in the equation of a line, y=mx+b
  14. 21. how close a measurement is to the correct value for that measurement
