Measurement Include:
Answer: Limitations Of The Measuring Device. And The Skill Of The Person Making The
Measurement.
The Mass Of A Block Of Wood Is Reported As 458 ± 21 G. What Is The Percent Uncertainty?
Show Your Work (2 Points For Correct Setup, 2 Points For Correct Calculation, 1 Point For
Correct Number Of Significant Figures)
Answer: 21/458x100=4.5852=4.6%
The Time For A Drag Race Is 14.5 S ± 8.1%. What Is The Absolute Uncertainty? Show Your Work
(2 Points For Correct Setup, 2 Points For Correct Calculation, 1 Point For Correct Number Of
Significant Figures And Label)
Answer: 14.5 S X 8.1% = 1.1745 → 1.2 S
Covert 50 Km To Meters.
Answer: 50 Km * 1000 M/1 Km= 50000 M
Covert 53 Mg To Grams.
Answer: 53 Mg * 1 G/1000mg= 53/1000= 0.053 G
A Person Runs A Race In 6709 S. How Many Minutes Is This Time?
Answer: 6706 S* 1 Minute/60 Sec= 6706/60=111.767 Minutes= 111.8 Minutes
What Do You Get When You Divide 932.0 M By 42.00 S?
Answer: 932.0 M/42.00 S= 22.1905 M/S= 22.19 M/S.
, In An Experiment, The Factors That Affect The Time It Takes A Ball To Fall Are Being Tested.
During One Set Of Trials, The Height From Which The Ball Is Dropped Is Systematically
Increased, And The Resulting Time It Takes The Ball To Fall Is Measured. The Entire Time The
Same Ball Is Used. Identify The Independent Variable, The Dependent Variable, And The
Controlled Variable.
Answer: Independent- Height Of Ball Dependent- Time Of Fall Of Ball Control- Mass Of Ball
In A Meaningful Paragraph Or Two, Describe The Role Of Experimentation In Science. Be Sure To
Describe How Experimental Data Can Affect Our Knowledge Of The Universe And How The
Reliability Of Information Is Affected By The Presence Or Lack Of Experimental Data. 4 Points For
Describing The Role Of Experimentation In Science, 4 Points For Discussing Reliability Of
Information And 2 Points For Grammar - Total 10 Points
Answer: Experimentation Is Extremely Important To The Field Of Science And Follwing The
Scienttific Method. When Something Wants Within The World Of Science Wants To Be
Explained, Scientist Can Produce Experiments In An Effort To Gather Data, Draw Conclusions
And Publish Laws And Theories. The Set Up And Design Of These Experiments Are Extremely
Important As They Must Be Set Up In A Way That Mimics Real World Applications And
Reproducable Conditions. Without These Aspects, The Data Drawn May Not Be Correct Of Fit
What Is Actually Trying To Be Studied. If The Set Up To An Experiment Were Not To Be Precise Or
Use The Correct Materials, Data May Be Skewed (Or Biased) Based On Any Number Of Factors.
In An Effort To Have Strong, Reproduceable Date, These Experiments And Their Setups Must Be
Reliable. Down The Line, Should An Experiment Want To Be Reproduced By The Same Team Or
Others, The Design Should Be Such That Not Only Can It Be Reproduced, But Also Acheive
Similar Results.
