Unit 1 (Measurements) Flashcards
The energy associated with the motion of an object
Kinetic Energy
The energy associated with the position/composition of an object
Potential Energy
Energy associated with the temperature of an object
Thermal Energy
Energy is always conserved in a physical or chemical change; it is never created nor destroyed
Law of Conservation of Energy
The amount of energy required to increase the temperature of 1g H2O

How close the measured value is to the actual value
Accuracy
How close a series of measurements are to one another or how reproducible they are
Precision
The result of these problems carries the same number of decimal places as the quantity with the fewest decimal places
Addition and Subtraction
The number of significant figures in the result is set by the original factor that has the smallest number of significant figures
Multiplication and Division
