Lesson: Combining Uncertainties Physics • 9th Grade

Students will be able to

• recall that when two quantities, and , are added together or subtracted from one another, the uncertainty of the result is equal to the sum of the uncertainties of and (if , ),
• recall that when two quantities, and , are multiplied or divided, the percent uncertainty of the result is equal to the sum of the percent uncertainties of and (if , ),
• recall that when a quantity, , is raised to a power, the percent uncertainty of the result is the percent uncertainty of multiplied by the power (if , then ).
