The Language of Physics: Quantities and Units
Across
- 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
- 6. the vertical, or y-axis, variable, which changes with (or is dependent on) the value of the independent variable
- 7. the SI unit for length, abbreviated (m)
- 8. the size of a quantity in terms of its power of 10 when expressed in scientific notation
- 9. 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
- 11. how close a measurement is to the correct value for that measurement
- 13. units that are derived by combining the fundamental physical units ]
- 16. when writing a number, the digits, or number of digits, that express the precision of a measuring tool used to measure the number
- 17. a ratio expressing how many of one unit are equal to another unit
- 20. the SI unit for mass, abbreviated (kg)
- 21. inches, foot, miles, pound.
- 22. how well repeated measurements generate the same or closely similar results
- 23. 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
Down
- 1. any relation between variables where one variable decreases as the other variable increases
- 3. relation between variables that produce a straight line when graphed
- 4. the horizontal, or x-axis, variable, which is not influence by the second variable on the graph, the dependent variable
- 5. a relation between two variables expressible by an equation of the form y=k/x
- 10. relation between variables that can be expressed in the form y=ax^2+bx+c , which produces a curved line when graphed
- 12. 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
- 14. a quantitative measure of how much measured values deviate from a standard or expected value
- 15. meter, kelvin, kilogram, ampere
- 18. a quantity that does not change
- 19. the SI unit for electrical current
