Document Summary
Types of uncertainties: an absolute uncertainty is denoted by the symbol and has the same units as the quantity, a relative or percent uncertainty is denoted by the symbol and has no units. To convert back and forth between the two types of uncertainties consider the following: m = (3. 3 0. 2) kg = (3. 3 kg 6. 1%) The absolute uncertainty is: m = 0. 2 kg = (6. 1/100) x 3. 3 kg. Completing uncertainty calculations: addition and subtraction: add, multiplication and division: add. Consider the numbers: (6. 5 0. 5) m and (3. 3 0. 1) m. Add: (6. 5 0. 5) m + (3. 3 0. 1) m = (9. 8 0. 6) m. Subtract: (6. 5 0. 5) m - (3. 3 0. 1) m = (3. 2 0. 6) m the relative uncertainties. Consider the numbers: (5. 0 m 4. 0%) and (3. 0 s 3. 3%) Multiply: (5. 0 m 4. 0%) x (3. 0 s 3. 3%) = (15. 0 m s 7. 3%) Divide: (5. 0 m 4. 0%) / (3. 0 s 3. 3%) = (1. 7 m/s 7. 3%) the.
