Compare your measurement to the generally accepted value of g (from a textbook or other source). Does the accepted value fall within the range of your values? If so, your experiment agrees with the accepted value. If not, describe why it does not. Make sure to calculate the percent error for the experiment.

surface, denoted by “g”. In this imaginary experiment, you have measured g three times. The values you obtain are:                 g1 = 10.2 meters per second squared  (m/s2)                 g2 = 10.4 m/s2                 g3 = 10.0 m/s2   To find the Average Value of g, denoted by gav, simple add up the experimental values and divide by the number of experimental values you have:                              g1 + g2  + g3         10.2 + 10.4 + 10                  gav  =  __________  = ____________  =   10.2 m/s2 .                                   3                           3                                  Percent Error (PE)   To find the Percent Error (PE), you compare the average experimental value to the standard or handbook value of the physical quantity you are measuring. The Standard Value of gravitational acceleration at Earth’s surface , gst, is 9.8 m/s2.         Mathematically, PE is defined as:                                           (Average - Standard)…

What is the difference between accuracy and precision? Explain 2. Calculate the volume and percent error/uncertainty in the volume of a rectangular sample block of length 13.51 ±0.05 cm, width 6.23 ±0.02 cm, and thickness of 1.76±0.02 cm. 3. Calculate the mass density and uncertainty in the mass density of the sample block. Mass of the block is 289± 1gr. 1.

A marathon runner completes a 42.188-km course in 2 h, 35 min, and 39 s. There is an uncertainty of 28 m in the distance traveled and an uncertainty of 1 s in the elapsed time. (Give all answers to the appropriate number of significant figures. Note that uncertainties should be reported to one significant figure and percent uncertainties should be reported to two significant figures.) (a) Calculate the percent uncertainty in the distance. _________% (b) Calculate the percent uncertainty in the elapsed time. __________%
