Physics Lab Practical ACTUAL UPDATED QUESTIONS AND CORRECT ANSWERS
Lab 1: Measurement |True value- Measured value/true value| * 100
How do you find percent error? **there is a percent error program
Lab 1: Measurement pi * radius of the circle squared
How do you find the area of an object? **there is a circle area program
Lab 1: Measurement (4/3)piR^3
How do you find the volume of an object? **there is a sphere volume program
Lab 1: Measurement The purpose of this experiment is to become familiar with methods of
measurement and error.
What was the purpose of this experiment?
, Lab 1: Measurement Meter, Kilogram, Second
What is the standard unit for length, mass, and time in the
MKS metric system?
Lab 1: Measurement Units are important because they allow for a comparison to a standard which
helps to understand the results.
Why are units important when reporting the result of a
measurement?
Lab 1: Measurement 1.21 %
An object is estimated to be 2.5 cm long. When
measured with a Vernier caliper its true length is
determined to be 2.47 cm. What is the percent error of
the estimated value?
Lab 1: Measurement xyz= 7.6 x 10^5
Complete the following calculations using the x+z= 23.81
explanation of significant figures given below. When
multiplying and dividing several quantities, the number of
significant figures in the final answer is the same as the
number of significant figures in the quantity with the least
amount of significant figures that is being multiplied.
When adding and subtracting several quantities, the
number of decimal places in the result should equal the
smallest number of decimal places of any term in the
sum.
Given: x= 12.24 y= 5400 z=11.572
Determine:
xyz=
x+z=
Lab 1: Measurement A stopwatch has precision to the hundreds place whereas the reflex testing is
precise to the tenths place so there is a limit to its precision.
Consider the results of your reflex time measurement.
What precision, in fractions of seconds, can you claim for
the stopwatch?
Convert the following measurement: 45.4 mm
4.54 cm to mm
Convert the following measurement: 4540 grams
4.54 kg to grams
